at least i've heard of Archos... what little info i can find on the ampe is mixed.
Mixed reviews is exactly what you will get with Archos as well. I don't understand paying 30% more for the Archos name, but everybody has their comfort zone.
The Ampe A10 and the Sanei N10 are the same product, if you are looking for more reviews/user experiences. Also, let me clarify: I'm not trying to push you to buy the Ampe tablet, just giving my opinion of the relative quality and reputation of Archos products.
