Other.
The proper term, I think is: good-enough.
It is a minimum-frills reader roughly comparable to the Kobo but trading off the eink for LCD.
It reads epubs, pdfs, rtf, and html quite well.
It talks to Adobe Digital Editions on the PC just fine, as well as the Kobo PC app. It also works fine with Calibre.
It uses an onboard database to track and manage the books so it can have issues if you feed it a *lot* of new books at once. (Much as the Sony 505, at that.) It is s-l-o-w to add even a handful of books. And the books show up on a single listing, either in a 3x3 Covers view or a thumbnail-plus-text vertical tile list. No pure text listing. So expect a *lot* of paging if you feed it thousands of books via SD Card.
It helps a bit that it segregates epubs from the document files so the later have a separate tab, DOCS, and listing. But that's it.
While reading, you have a choice of serif or sans-serif font face, 7 brightness levels, day, night, and sepia Themes, and about 7 font sizes. As with most mobile ADE-based readers, one could wish for both smaller and larger sizes.
It is supposed to be limited to 8GB SDHC cards but I fed it a 16GB MicroSDHC in an adapter with no issues; it saw all 16GB and reported the correct amount of free space. Books opened fine, too.
Online connectivity to the KOBO stores works but it seems to prefer encryption-free connections. (At least it didn't get along with my router with encryption on.)
Paging speed is good, even with PDFs.
And I've yet to see a crash while reading.
So, no; it is not the best ebook reader out there.
And it lacks all sorts of user controls and file management features that the best readers offer.
It's no Pocketbook or even Kindle.
But it's good enough to read on (if you don't mind the snowboard form factor) and fairly priced if you can get it in the US$69 range (do an online search--they're still out there) and a bargain at $39.
It is far from the worst reader you could get, especially if you favor color LCD over eink displays. And, hey, it comes with a cover!
