Ya, CES is releasin' quite a few. Asus, Toshiba...I think Motorola.
I've played with the Nook Colour (only web surfin') and I was impressed with the loading times, but scrolling was jumpy...no pinch zoom either. Didn't realize it could be jailbroke though.
I've only read user reviews of the Archos and not to many people said good things about it. Mostly was wait for Honey...
I'd save that $300 for a while and get something in the $500 range.
