Good to see, after some initial confusion, that the PB support staff have come through (again) to help customer. Of course it's a shame that there was any problem, but overall I think the PB devices are pretty good quality and reliable.
I am still using 14.2 on my PB360 and have no desire to change yet. I sometimes get the urge to upgrade because usually a newer firmware should be better, but the 14.2 config on my PB360 has been almost bulletproof since Dec 2009, and I am thus hesitant to change something that isn't broken!
If I used ADE I would probably be more motivated to change, but I read almost exculively in FB2 and use the fbreader180 with wrist-turn app and am loving the reading experience. Well done to all involved in the PB devices, support and the developers of 3rd-party apps like fbreader180.
I recommened PB to anyone who asks about a choice in eBook reading devices, with the caveats of my own usage requirements, of course...
Keep up the good work!
