For now, B&N only advertises its iPhone, BlackBerry, and PC/Mac software readers on its site, but the company doesn't offer any compatible hardware readers just yet. Since the launch of the eBook store, B&N has announced a partnership with iRex and we are still waiting for the mythical Plastic Logic eReader to appear.

A spike in interest right after the launch of a new product is obviously nothing unusual, but this data shows that B&N could challenge the Kindle in the long run. To do so, however, B&N needs to offer users a clear alternative to Amazon's Kindle. Sony, which offers numerous eReaders that are connected to its eBook store, is obviously also trying to make a major push in the eBook market and while its numbers are slowly trending up, Amazon and the Kindle remain in a clear lead. As Compete's McGovern points out, B&N has shown that it can easily drive its customers to its eBook store - thanks, in no small part, to a very successful email campaign - but it will need to offer a hardware eReader to really take on Amazon.

We tested the iPhone app yesterday, and it is indeed a very capable eReader app. It especially stands out because it gives users the ability to customize everything from background and text colors, to what gesture users prefer to switch pages (swipe or tap), as well as line spacing, font size, and margins. The desktop app, which we tested on a Windows PC, is also very usable and customizable, but doesn't feel quite as elegant as the iPhone app.

While the apps are good, though, the B&N eBook store will only be able to really live up to its potential once the company starts to sell the Plastic Logic eReader. While the Kindle is a great device, there can be no doubt that the design is a bit clunky. The Plastic Logic reader, however, looks quite slick, and thanks to its touchscreen, it also offers a sought-after capability that the Kindle currently doesn't offer. In order to compete with Amazon, though, B&N will have to sell the Plastic Logic reader at a price that compares well with Amazon's Kindles.

Wireless Store?

One feature that makes the Kindle stand out from its current competition is the ability to buy and download books wirelessly directly from the device. According to Plastic Logic, the company's eReader will also be able to transfer information wirelessly, though it is not quite clear if this will mean that B&N will partner with a wireless provider, yet. If B&N and Plastic Logic decide against this, though, this could give users an important reason to shun B&N's eReader/eBook store combo.

Can Barnes & Noble Compete with Amazon?

In the perfect world, it wouldn't make a difference whether you prefer a Plastic Logic reader, a Sony Reader, a Kindle, or an iRex iLiad. The Kindle has shown (and so did the iPod before it) that having full control over the hardware and content typically results in a more convenient and attractive package for consumers. In the long run, this will probably (hopefully?) change, but for now, we think B&N is doing the right thing by copying this model for its eBook store, though we will have to wait until the roll-out of the Plastic Logic eReader and how consumers react to it before we can really render a final verdict.

As B&N decided not to compete on price (it sells most eBooks for the same $9.99 as Amazon and also offers free samples for every book, as well as a selection of books for under $5), the quality of the hardware, the number of available books, the openness of the store, and the quality of B&N's service in general will be the areas where the company will have to stand out. Given what we have seen so far, we think that Barnes & Noble might indeed be able to challenge Amazon's position in this market, especially given that we are still in the early days of the eBook and only a few consumers have picked sides at this point, and even fewer have actually bought an eReader yet.

Plastic Logic's Reader

The first product on our list is Plastic Logic's upcoming e-book reader. A demonstration of this device at the past DEMO08 conference left many people amazed at how incredibly thin this potential "Kindle-killer" is. The company says they've perfected a way of printing polymer transistors onto flexible plastic displays. This particular revolution won't be just a transition to lighter and "bendier" touchscreens, it will also lead to lower power consumption and longer battery life.

But perhaps what's best about Plastic Logic's technology is the cost. The polymer-based circuitry will be able to bring new products into market where silicon microchips were simply too expensive. Since the displays are flexible enough to be rolled up like paper, the potential for this new type of computing is nearly limitless. Is this the future of the newspaper? Perhaps, but it could also be used in smart electronic tags that track merchandise and large flat-panel displays.

Plastic Logic will begin their entry into the market in the second half of 2009 with pilots and trials with key partners and will prepare for further sales by 2010.

Pressure-Sensitive Computing: Impress

For an inventive, "out-there" product that could make the cold, stiff computer a thing of the past, look no further than this touch screen flexible display called "Impress" (PDF). Made of foam and force sensors, Impress works with both touch and the intensity of pressure. This computing technology lets the user squeeze out information or put objects in motion by deforming the surface of the computer.

The end result is pretty amazing, though it may not end up being as practical as the flexible polymer displays. However, it's easy to imagine how it could be put to use in entertainment-based computing at the very least. (Or maybe huggable, touch-enabled teddy bears? We can only hope!)

The Touch OS: Windows 7

While its easy to see the usefulness of touchable handheld devices, others have questioned how exactly touchscreen computers - such as the upcoming Windows 7 OS - would be useful to consumers. Suggestions have included everything from control panels for the smart home to kitchen PCs for touch-based recipe look up to touchscreen Media Centers. However, the answer as to what could really impact touchscreen PC adoption may be as simple as this: games.

At this year's CES, a demo of a Windows 7 air hockey game demonstrated the potential for a new type of human-computer interaction...like an iPhone but much, much bigger.

In addition, Microsoft also introduced two new Surface applications for Windows 7 at CES as well. One that allowed for photo manipulation and another for interacting with maps.

Yet there still is a question as to whether the iPhone-like multi-touch capabilities of a touchscreen OS will become as big of a hit in traditional computing as they were on the smartphone.

These above examples of touchscreen-based computing demonstrate the new ways we may interact with technology - and therefore the web - in coming years. It's a glimpse into the future of a world where our interactions with technology come more easily and more naturally than ever before. This trend will continue to move computing away from being an activity for technophiles alone and will make it an activity that everyone - even mainstream users - will enjoy.
