The iPad isn't just a hot new consumer device, it's also an increasingly popular tool for business. Each week we take a look at the new or updated business apps for the iPad, and highlight trends in how tablets are being used in the enterprise.

This week week we look at the updated Adobe Connect app, TripIt for iPad, Oracle Business Intelligence Suite and more.

Global enterprise software revenue increased 8.5% to $245 billion in 2010 according to Gartner. Enterprise software sales declined 2.5% in 2009, so this is encouraging growth for enterprise software vendors.

The growth beat Gartner's forecast from last September, which put enterprise software revenue at $232 billion for an increase of 4.5%.

Today, Adobe revealed three new Photoshop Touch applications designed for the iPad: Adobe Color Lava, Adobe Eazel and Adobe Nav. The apps work with Adobe's Photoshop CS5 desktop software, which will be updated to version 5.5 in order to support the new functionality. The update is due out in a matter of weeks.

What's interesting about these applications - not Photoshop replacements themselves - is how they integrate the tablet with the PC, offloading specific tasks to the touchscreen interface. In Color Lava, for example, artists use their fingers to mix colors on the iPad, creating custom swatches and themes which can then be ported back to Photoshop. Adobe Nav, meanwhile, offers a different way to navigate desktop Photoshop's interface. Only in Eazel are actual paintings created - but paintings which take advantage of the touch technology to offer new techniques in blending paint.

In addition, third-party developers will soon be able to integrate similar functionality into their apps, thanks to Adobe's new toolkit, the Photoshop Touch SDK.

Today, SublimeVideo, a cloud-based HTML5 video player service, is launching commercially with plans starting at under $10 per month. Developers will also have access to a free, unlimited plan which they can use for testing purposes. The service, developed by Switzerland-based development and design firm Jilion, allows Web publishers to easily deploy HTML5 video on their websites, without needing to understand the complexities of different browsers versions and their associated specifications.

Instead, with the SublimeVideo service, a plugin-free Web player is provided that uses HTML5 to display the embedded videos Web publishers want to host online. When a user visits a site using an older browser, a "fall back to Flash" mode switches the player to use Adobe Flash technology for more universal compatibility.

HooteSuite wasn't the only company to announce a social analytics suite yesterday: Adobe announced the addition of a new product called SocialAnalytics to its Online Marketing Suite. SocialAnalytics will ship in Q3 and monitor Facebook, Twitter, YouTube and many other sources.

Online Marketing Suite already features various tools for social media monitoring, but this new package extends the suite's capabilities by adding features for determining a business' top influencers, tracking sentiment over time and calculating how much revenue is generated by social media campaigns.

Today Adobe is launching an experimental Flash-to-HTML5 conversion tool called Wallaby. The tool takes content created with Adobe's Flash Professional and converts it to HTML5, the latest revision of the Web markup language. HTML5 is supported in most Web browsers, but, most importantly, it's supported on Apple's iPhone, iPad and iPod Touch, where Flash is banned.

This week at Mobile World Congress in Barcelona, Adobe provided an update on how its Flash and AIR technologies have performed over the course of 2010, specifically in terms of penetration results. Thanks in no small part to the rise of Android devices, Flash adoption has topped Adobe's earlier forecasts. At the Adobe MAX Developer Conference earlier last year, Adobe had forecasted 9% of mobile phones would support Flash in 2010, but as of year-end, the actual number was 12%.

There are now 35+ certified mobile devices that support Flash, says Adobe, and 20 million mobile phones running the plugin.

Adobe is announcing at Mobile World Congress that its digital publishing suite, which allows content publishers to craft magazine-like content for tablet computers, is now going to be available for Android in addition to iOS. Already, the Adobe software has been used to create over 100 publications that run on iOS devices, including big names like Wired, The New Yorker and Empire.

With the introduction of the Content Viewer for Android, the resulting publications will run as Adobe AIR applications on Android-based tablets.

All the buzz about HTML5 in 2010 and the Apple/Adobe rift makes it pretty easy to think it was a grim year for Flash. But the Flash team at Adobe wouldn't agree. They've posted The Flash Platform Top 10 for 2010, an interesting list reminding us that 2010 was actually a pretty good year for Flash developers. Apart from all the worrying that the sky was falling or that their skill set was going to go the way of horse-drawn carriage repair.

The preview of the Melrose Beta SDK from Adobe allows for Adobe AIR apps to be integrated into online stores such as the Intel AppUp center. The Atom Developer Program offers the SDK and accepts AIR apps. Now that AIR applications are supported in AppUp, it's probably a good idea to take inventory of what this means for developers.
