I have the non-lite version, and in hindsight, I might not buy one. I love the screen, the compact size, and the general ease of use. Ask me on a bright, beautiful summer day from my hammock and I'd say "of course". But it's a dark winter's night here.
The lack of hyperlinks and multiple fonts would make me think twice. Lack of DRMed formats (on the non-lite) is iffy. Since they're not there, they can't screw things up. OTOH, having them, assuming they're implemented properly, it does allow additional capability.
A definite maybe.
