Well, everybody and their sister are looking to be more environmentally friendly, and I'm no different. I read quite a few books within the span of a year or so, so saving trees is becoming quite the priority for me personally (and buying used real books doesn't seem to ease my conscience...).
Here are my main requirements:
- Easy to use (total dealbreaker if it's not easy to use)
- e-ink display (doesn't have to be color, but dealbreaker if it isn't e-ink)
- PDF support (isn't an absolute dealbreaker requirement, but it'd be nice nevertheless to have true PDF support without some sort of stupid workaround if absolutely necessary)
- Ability to sync with Macintosh (in the case of Kindle, what if I'm in a wireless dead zone? If I can't sync with a Mac, it's a dealbreaker for me)
- Ability to purchase eBooks and be able to read them within a few hours (left intentionally broad for a reason)
I think that covers it. So, any thoughts? Any suggestions?

in advance for your advice.
