I've been using the Doxie Q for about a month now and I'm quite happy with it. I love the portability. Battery life has been excellent. I haven't worked it very hard, but I've used it several days in a row without charging. Scan quality has been adequate for my needs, in fact, I've typically left it at the 300 DPI setting. I've mostly been scanning paper documents. I usually transfer scans to my laptop using the SD card, which works well, and the software is easy to use. A few times I've transferred to my cell phone using the WiFi connection. It works okay. The WiFi interface is a little clunky, but functional once you figure it out. Sometimes feeding paper in takes a little coaxing to get it to the rollers. My large fingers occasionally have trouble with the DPI and Scan buttons. I find I accidentally hit the DPI button when I mean to hit Scan, and vice versa. Not a huge problem, but it would help me if the buttons were spaced apart a little more. But overall, I'm very satisfied with the purchase.
