[Q]: my scanner hasn't worked since the day i took it out of the box, installed the software, and the green light is on but when i hit scan it does nothing! looks like it's a dud. lol.
[A]: Negative


[Q]: The book covers several generations, so with each generation you have to re-learn all the characters. It is difficult to keep track of who's who when every time you get to know the cast, 200 years suddenly pass and we're in the middle of a new crisis. I didn't read the whole series because of this -- it was obnoxious.
[A]: Negative


[Q]: I've already dropped it, (unit was off) and it's fine. It's a little larger than I expected, so is more of a pocket unit than an armband or clip-on. The creative software is not too good - I did some searching and found some recommendations for Notmad Explorer - which does truly rock as accessory software for the Nomad. It will copy over playlists from most other media players without a hitch- which was problematic with the Creative application. Overall I'm pleased with the purchase.
[A]:
Positive
