Interesting device, thanks for the review.
I think some tests or benchmarks of actual book reading experience could be useful too.
For example, my Kobo times out on complex ePubs, making them effectively unreadable. Like technical books with lots of syntax colored code: using the TOC to jump to chapter X will just hang until the watchdog reboots the whole thing.
So this is perhaps a more useful way to test the CPU than a 3d benchmark or website load time? :-). Cheers
