I got it! It's tiny, especially compared to my 950, but very cute.
Sony's software does not recognize my new little baby, but Calibre does, and calls it a Jetbook, which I understand is the same device, just different print on the front. It's plugged in through USB right now and telling me it's charging, so I will go through the firmware thread later and see if it needs updating or not. I expected it to come with a 2GB SD card, but looking through the documentation in the package tells me it's not included, so I need to get one. I have 10MB storage right now... not nearly enough for my Calibre library.
So far, so good. The little one is very different from the 950 (nearly 20 buttons!
), but it has lots of potential. I will play with my new little eReader this weekend and figure out his place in my gadget family.
