I bought the original Kobo when it came out and I absolutely hated it. It's only good for reading ePub materials, even though it supports PDF files. As a student, I thought it would be great for bringing all of my course materials to class. Alas, not all PDFs are created equally, and I abandoned the idea after discovering that many of my history course documents would not zoom in to a legible size without being too wide to read without scrolling side-to-side.
I did, however, start using the Kobo software app on my laptop and iPhone 2 years ago, and I loved it. I used to read on my long bus commutes that way while I was living & attending school in British Columbia. I think that's the only reason why I gave Kobo a second chance when they unveiled the Vox, and I'm glad I did.
The Kobo Vox is the first colour touch screen tablet produced by Kobo, and it's built on an android platform. I enjoy using it for games and casual internet usage when I'm away from a computer just as much as I enjoy using it for its primary purpose - reading - and I take it everywhere. My only complaint, given that I'm willing to ignore certain deficits in the primitive web browser, is that I cannot for the life of me figure out how to put PDFs on it. It doesn't work the same way older models do. I have a few ebooks that were self-published by authors I know or acquired before ereaders and ePub editions were widely used, which are all simple PDF files, and now I can't put them on my favourite reader.
