It seems that until January 2013,
very few companies will be able to make Windows RT tablets.
Apparently each of the licensed chipset maker was able to chose two tablet manufacturers.
That article says it'll be like this:
- nVidia for Lenovo and Asus
- Texas Instruments for Toshiba
- Qualcomm for Samsung and HP
It's really weird that Acer isn't in that list, as they have experience in both Google and Windows tablets. Lenovo and HP, on the other hand, don't seem to have been very successful in the tablet market. Toshiba is also a bit questionable, they've put out some despicably bad tablets in 2010/2011.
Moreover, there won't be a single Rogue GPU in the first batch of Windows RT tablets.
