Steve Jurvetson, one of the best-known technology investors in the world, has posted an updated version of Kurzweil's visualization of the history of exponential growth in computing. In his thought provoking discussion of the phenomenon, Jurvetson calls this "the most important chart in technology business."

"What Moore observed in the belly of the early IC [integrated circuit] industry was a derivative metric," Jurvetson writes, "a refracted signal, from the bigger trend, the trend that begs various philosophical questions and predicts mind-bending futures."

What will be the next big leap in computing technology? From a hardware perspective I won't even venture to guess, but it sure is exciting to think about what those technologies will enable. Many things we'd love to see done today remain too processor intensive, from advanced Augmented Reality implementations to broader real time services and machine learning. Ultimately, we can only make clumsy guesses about the killer apps of an exponentially more powerful computing platform - that's the point.

When calculations per second increase exponentially, fundamentally new things become possible. It's one of those fascinating quantitative changes that cross the threshold of creating qualitative change.

For every frontier explored there is baggage brought from home, of course. About this chart, Union Square Ventures associate Andrew Parker asks "how much does a newer medium pull from an older medium in terms of design paradigms?" (That makes us want to cry for the poor limping US Patent Office, now facing layoffs of all things!)

Mind bending is right. What does this chart, that Jurvetson calls the most important in the technology business, bring to your mind - innovation loving readers of ReadWriteWeb?

Linux Makes Netbooks Even More Affordable

In the rest of the computing world of desktop computers and mainstream notebooks, you're typically choosing between Windows Vista or Mac OS X, but in the world of netbooks, it's Linux or XP. Those two operating systems are perfect for netbooks thanks to their lower CPU and power requirements.

For those pinching pennies (and who isn't these days? ), the Linux netbooks are even more affordable than their XP counterparts, typically falling into the $300-400 range. If you're already doing most of your computing in the cloud - that is, you use webmail, create and edit documents using a service like Google Docs or Zoho, store your photos online at a site like Flickr, and, most importantly, don't need to run a bunch of software programs on your desktop, the Linux computer is now looking more like a viable option than before - and one that saves you a bit of change too. Just look at these prices: the Acer Aspire One ($399), the HP Mini 1000 ($379), the Dell Inspiron Mini 9 ($349), and the MSI U90X ($369).

Breaking Into Mainstream

As any Linux fan will tell you, the beauty of this OS is its stability. These Linux machines don't crash, boot quickly, and are generally known to be all-around reliable computers.

However, there are still a few folks out there who are going to go with the XP option for familiarity's sake. There's comfort in knowing that your peripherals will work and that you could run Windows-only desktop software if you needed to. Although there are tons of open source alternative software programs out there, an average computer user isn't likely to know what those are or how to find them.

Those issues still stand in the way of mainstream adoption, and have led some buyers to return their PCs to the manufacturers. An MSI executive, Andy Tung, recently reported on the high return rate of the Linux machines, saying: "Our internal research has shown that the return of netbooks is higher than regular notebooks, but the main cause of that is Linux. People would love to pay $299 or $399 but they don't know what they get until they open the box. They start playing around with Linux and start realizing that it's not what they are used to. They don't want to spend time to learn it so they bring it back to the store. The return rate is at least four times higher for Linux netbooks than Windows XP netbooks."

The Linux PCs may also end up getting a run for their money when Windows 7 is released to the wild as that OS is netbook-ready and easy on the CPU, memory, and battery use, according to the news coming out of this year's PDC.

Linux Gets A Foothold

That being said, this move to netbook computing is offering Linux a foot in the door of mainstream computing in a way that may have never been possible before. Without the economic crisis to factor in to people's spending decisions, people probably wouldn't have considered the Linux option as strongly as they're doing today. When every dollar saved counts, the decision to go Linux may be more about cost savings than anything else, but that might be what it takes to get people to try the OS computer geeks have been raving about for years.

Are you going to buy a Linux or XP netbook? If so, tell us which ones you like and what's factoring into your decision.

This is not the first time that Apple had issues with its power adapters. In August, Apple announced that it was investigating issues with its MagSafe power adapters for the MacBook and MacBook Pro line. According to some users, these adapters tend to overheat, short out, and burn.

With millions of iPhone 3G phones sold in the last few months, this is a major undertaking for Apple. The only advantage for Apple is that these power adapters are relatively inexpensive. Currently, replacement adapters retail for $29, though Apple's actual cost is surely a lot less. Apple will probably take a small financial hit from this, but the real question will be if the image of the iPhone will be tarnished by this recall - especially after so many users have already complained about other problems with the phone.

This is Part 1 of a 5-part series in ReadWriteWeb's Enterprise Channel. Part 1 covers everything from a physical perspective. What, ideally, you need to have to make the digital office run. In subsequent parts, we will cover browser, web apps, mobile, and more.

LAPTOP

Recommendation: The Mac Book Pro

Why?: Primarily, OS X - arguably the best operating system out there. In terms of hardware however, the MBP's form factor, strength, wireless connectivity, long battery life, speed, memory, improved graphics card, multi touch trackpad and decent sized hard drive all wrapped up in a beautiful metallic case should be enough to convince you.

Asus U2E, Sony Vaoi TZ31MN, Macbook, Macbook Air, Asus EeePC 900

PHONE

Recommendation: Blackberry Bold

Why?: Let me be clear. I'm an iPhone user and I'll openly admit I have yet to use the blackberry bold. However, I have used almost every previous blackberry and from reviews by gizmodo, engadget and a number of gadget sites - this is the best blackberry ever. However, the main reason I have selected the Blackberry Bold over the iPhone is because of the downfalls of the current 3G iPhone rather than the excellence of the Blackberry Bold. Running your digital office you need to ensure you have access to your email, contacts and a solid long lasting battery - the iPhone is still not reliable enough on both of these points. If this post was more about the Social Media Guru's device list... yes, the iPhone would definitely be my phone of choice. Although of course, with an external battery attachment! We are, however, discussing the digital office and the iPhone is not there yet and won't be until battery life is extended, bugs are ironed out, multifunctionality between local apps is implemented and yes, email and connectivity issues are corrected.

Price: $400

Why?: It's not perfect however you'd be hard pressed to find a better all round device at this size out there. Glorious screen quality and device build. Setup is elegant and straight forward as you would expect. Navigation is equally impressive. Youtube is so easily accessible, accessing e-mails works flawlessly, battery lasts well to listen to music but runs low fast when on the youtube or internet. For such a small thing it can do so much: Games, Calendar, Mail, Internet, Music, Movies, Apps... What are you waiting for? The only real competition in my mind is the iPhone.

Alternatives: Archos 605 Wifi, Microsoft Zune

HEADPHONES

Recommendation: Shure Se210 Sound Isolating Earphones

The server, called the IBM iDataPlex, is a blade server running Linux and utilizing Intel's quad-core Xeon processors. The system is designed to directly compete with the "white box" servers that are commonly used by internet companies.

In addition to being extremely powerful, the iDataPlex also introduces what can be considered "green" features. That is, the sever uses 40 percent less power thanks to its efficient cooling system and unique form factor.

Traditionally, cooling systems blow air over servers back to front, and, as servers go deeper, more energy is needed to cool them. With the iDataPlex, the server is wider, but smaller - only 15 inches deep instead of the typical 25, which lets the fans run at a lower velocity, saving "about 67 percent on the fan energy alone," said Gregg McKnight, CTO of IBM's modular systems group, in an InfoWorld article about the system.

Additionally, an optional liquid cooling system allows the iDataPlex to run at room temperatures, no A/C needed. This will be a big help to the companies whose servers run out of these massive data centers today - often spending 10 - 30 times more on energy costs per square foot than a typical office building due to the need to power the servers and cool them.

Even without watercooling iDataplex is still at least 20% cooler then the conventional rack approach. This photo (above) was taken in IBM's Thermal Lab, showing the iDataPlex without the liquid cooled door (red) and with it (blue)

A Change for IBM

Typically, IBM and other server vendors produce expensive, high-end machines that have high levels of redundancy, but for Web 2.0 companies, that level of redundancy is not needed. If a server drops off, it just stays dead while the rest of the cloud picks up the slack seamlessly. In companies the size of Google, for example, dead machines are just left on the rack.

It's clear that IBM sees the writing on the wall - the enterprise datacenters of the future are going to be all about virtualization, green IT, service management, and cloud computing. As part of IBM's "Blue Cloud" initiative, the iDataPlex is a sign of IBM's commitment to the emerging cloud computing platform.
