Microsoft has unveiled Surface - its own-brand family of tablets.
The touchscreen computers will be powered by its upcoming Windows 8 system and contain either an Intel or ARM-based processor.
The company's chief executive, Steve Ballmer, said it had wanted to give the software "its own companion hardware".
However, the move puts it into competition with other manufacturers who will also be releasing tablets designed for the system.
The devices have a 10.6 inch (26.9cm) display, are 9.3mm (0.4 inches) thick, have a built-in kickstand and are housed in a magnesium case - which the company described as the first of its kind.
Windows tablets from Asus and Toshiba at Computex should tell us more about the progress of Windows RT.

Asus, Acer, and Toshiba will out a mix of tablets based on both Windows 8 and Windows RT at the hardware-centric Computex trade show next week, according to Bloomberg.
Windows 8 will run on chips from Intel, while Windows RT is powered by ARM chips from Nvidia, Qualcomm, and Texas Instruments.
One Asus tablet uses an Nvidia chip, according to Bloomberg. CNET reported earlier in the month that Asus and Lenovo are expected to bring out Windows RT tablets built around Nvidia Tegra 3 chips.
A Windows RT-based Toshiba tablet is using Texas Instruments' silicon, according to Bloomberg.
This jibes with what sources have told CNET. Only a handful of Windows RT devices will be released initially from vendors such as Asus, Acer, Toshiba, Lenovo, and possibly Hewlett-Packard, as Microsoft wades slowly into new Windows waters. Windows RT is the first mainstream desktop-class Microsoft OS to run on ARM processors.
One of the burning questions is whether conference goers will actually be able to use the devices. To date, Windows RT tablets displayed at trade shows and conferences have been inaccessible -- always encased in glass.
Acer, meanwhile, will show a Windows 8 device running on top an Intel chip, according to Bloomberg. And Asus will show off a second device based on an Intel chip.
