Despite the iPad's long lead in the enterprise market, Apple's tablet PC performer will not last long according to an increasingly bullish Dell.

In a move away from the Android juggernaut, computer giant Dell has announced its new 10-inch business tablet, due in Australia later this year, will run the Windows 7 operating system.

With a plethora of tablet PCs hitting the market this year, CIOs and IT managers may be struggling to work out which device will best suit their needs. With a screen size of five inches, some may call the Dell Streak a small tablet that simultaneously acts as an oversized smartphone. Its compact nature and multi-tasking capability, however, makes for an extremely useful device that while may appear cumbersome at first, soon has you thinking you could never go back to the small screen of a smartphone.

Dell showed off a prototype of a 7-inch Android tablet this week at the Oracle Open World conference in San Francisco. While being more tablet-sized than Dell's initial anemic attempt at joining the tablet fray, this new venture still faces some challenges in order to compete.

Dell is trying to extend the appeal of its Streak handheld to businesses and add a new dimension to its enterprise hardware, software and services offerings, a company official said this week.
