Thanks for the congrats.
After a couple more hours with the eDGe I'm feeling pretty comfortable with the interface. One key thing was figuring out how to scroll with my thumb on the right part of the LCD touchscreen, and grabbing the knob/thumb thingie that pops out to scroll in larger increments. Very handy in the dictionary and on the SD card after I put over 300 ePubs on it.
Happy to see that reports of needing to add things to the library (onboard storage) in order to use them is not the case. I can open up books or video directly from the 16 GB SD card. (Though, darn, .mkv video isn't supported by the default player.)
I'd prefer more increments of zoom/font size in both PDF and ePub. I run into the same problem as on the iRex: Medium a bit too small but Large much too big (for example). My Cybook Gen3 has something like 16 increments in ePub, so it's not a limitation of Adobe-compatible ebooks.
Overall I'm liking it so far.
