Thanks for the welcome
Actually, I'm really eager to upgrade to the 700 for the searching/notating/highlighting, as well as the light, and the USB charging (I travel a lot). But for now I've decided to wait. When I tested out the unit in the store, it seemed like entering notes was a bit cumbersome. I think I had to first highlight (which wasn't a speedy thing in itself), and then double-tap (which I often had to repeat in order for it to work) before I could actually begin entering notes. The unit was buggy in general and kept crashing, so I suppose there's a possibility that entering notes is a smoother process on more functional units. Since that's one of the main features I'm looking to upgrade for, I figured I'd wait for the next generation.
I was also disappointed that the design emphasizes finger-swipe page turns instead of button page turns. I don't mind the feature, but I don't like how the buttons have been shrunken and are less ergonomically placed.
Maybe that all belongs in another thread, but to bring it back to the topic of this thread, I had no issues with the screen.
