I'm asking myself the same question. But after reading up on these units, I think the new E005F is the one to choose. Lightweight, small, decently priced for 2GB. Only thing that makes it hard to choose is the lack of a 3-line display. But then I think to myself, "Do I really need it?". No, I don't look at the screen all that much. Plus, apparently naviagtion is a breeze. And most importantly, it's the only one (so far) to offer fast direct USB charging without any cables, so no matter where there is a desktop/laptop, you can easily charge it (3 minutes for 3 hours fast charge). I think I'm going with this one!
