This isn't an Archos design. You might have noticed that looks a little like the Next2 I reviewed some time back. I believe it actually is the same hardware. You see, Archos work with the CPU maker RockChip, and that is who designed this ereader. I should know; I saw a very similar device in the RockChip booth at CES.
The Next2 was an okay set of hardware, but I've gotten at least one complaint about the current firmware (which the 70c will likely use). My friend is having a lot of trouble with reading apps; both the Kobo and Kindle apps have trouble downloading ebooks from the respective ebookstores.
