The computing giant announced the Latitude 6430u Ultrabook, Latitude 10 Tablet and the OptiPlex 9010 desktop PC to capitalise on the launch of Microsoft's next operating system.
The Latitude 10 Tablet is a 10-inch slate running the full version of Windows 8, with an Atom CPU processor and expandable SSD storage of up to 128GB, while the 6430u Ultrabook packs a third-generation Intel Core i3/i5/i7 processor, and up to 256GB of SSD storage.
Dell's OptiPlex 9010 is a touch-enabled all-in-one desktop computer powered by Windows 8.
"Never before has the intersection between great design and data security and manageability been as important as employees increasingly ask for support for gorgeous products while IT needs to maintain corporate controls," said Sam Burd, global vice president of the Personal Computing Product Group.
"Dell is providing the answer with these new Latitude and OptiPlex products designed to inspire workers and meet the needs of IT.
"Dell's approach is rooted in our heritage of deep familiarity with the needs of IT professionals combined with our new, world-class set of commercial products that meet user demands."
All three machines are expected to be available in late October to coincide with the release of Windows 8.
