Judging by the Spreadtrum-powered smartphone prices, this should mean some *really cheap* quad core tablets. Not sure how good their designs, support etc are though…

And the proverbial question, but does it support XBMC?

But can it run Crysis ? 😀

@Marius Hehe, yes that is what I was parafrasing here 😉

Everyone on the PC side want to know if a new GPU can run Crysis at high resolution with everything enabled.

However for SoC and media players we instead want to know if it runs XBMC with hardware decoding
