Welcome aboard Sam!
Oh, not to forget that SHARP zaurus is also a good option ... especially since it has a pretty strong community of users and developers for support!
There is also the Nokia 770 which has its own merits especially since its a product that is currently supported and developed by Nokia.
These two products have TFT LCDs instead of eink, but besides readability issues in direct sunlight, they are just fine, though eink readers win hands down in the battery life department!
