Android-based tablets could also find a home in the enterprise, Lalla said. In fact, with the tablet and smartphone markets still evolving, Dell is betting on all the horses -- Android, Windows, x86 and Arm-based processors.

It already sells the Streak 5 and the Streak 7 -- which are 5- and 7-inch devices based on Google's Android OS. The 5 has a Qualcomm Snapdragon processor and the 7 has a dual-core Tegra chip.

Dell also sells a smartphone called the Venue Pro based on Microsoft's new Windows Phone 7 software. It has a 4.1-inch touch display and a mini-keyboard that slides out of the bottom.

Gartner and IDC have both said tablets appear to be eating into PC sales, but Lalla said he expects sales to be additive. Some consumers have bought tablets as their primary device, but Dell expects them to be used more as complements in the business world.

All the new systems announced Tuesday -- apart from the Windows 7 tablet -- will start to ship in about a month. They use Intel's new Sandy Bridge chips, but Lalla said none of the products were delayed as a result of the glitch Intel reported with that platform last week. It appears Dell was lucky with its timing.
