I am liking my Glo but the font is a bit pale. The first day I had it I kept picking up my Kindle because the contrast was better but I am now only using the Kobo and am adapting to the lighter font. I'm not quite ready to get rid of the Kindle but am hopeful that I can become a Kobo convert.
It hasn't had any glitches (I know to avoid the desktop app and just stick to Calibre and ADE) and the light is great. It is very evenly distributed.
