Hi, looking for some advice on what might be good for my wants. I've heard the Sony's are very good quality. But pricey, except for the 300 series model but that doesn't have an SD slot. A coworker who has one says the B&Noble Nook is a "dog", buggy and slow, and that B&N (like Amazon) "tries" to lock you into buying ebooks only from them. (or make it harder to put on the free books?) He also said the cheaper ereaders often have crappy software, and their e-ink quality may not be so great. I like the fact he has language dictionaries and touch screen on his 300 model. However, for eink, I don't think having to use a clip on light at bedtime in the dark is so great though, although of course I understand lack of backlight saves batteries. He also touts e-ink readers as lasting weeks without recharge. But I read the Nook lasts 10 days. (quite acceptable I feel) I asked him about wi-fi, if it can be used for browsing web sites, and he seemed to say it's only for buying books. Is that correct?
I'd like to checkout ebooks from my library. It appears they offer Adobe epub, Adobe pdf, Mobipocket, and Overdrive WMA or MP3 audiobooks. So something that supports all these would be nice. I'd want it to be able to use ALL popular FREE open-source file formats too. I've seen folks on the bus holding giant sized ereaders. I wouldn't want that....His Sony 300 looked like a nice, portable size.
