The same source didn't give away much info on the Lenovo tablet except to say it will have an Intel produced processor. One possible device that would make an impressive debut for the OS would be the Lenovo IdeaPad Yoga which was seen at this year's CES and sports a 13.3 inch display. The device has an attachable keyboard on a 360 degree hinge that allows you to convert it into a laptop.
Besides Dell and Lenovo, other manufacturers are going to be hard at work to grab some of the Windows 8 market share including Nokia, HP, Sony and Asus. According to Microsoft's tablet requirements, any Windows 7 device will be able to use Windows 8. If the model supports five touchpoints, has a variety of sensors and is equipped with certain hardware buttons, it also could be marketed as a Windows 8 device.
