I was looking for an mp3 player with a lot of storage and the Treo seemed to fit the bill. With 15gb hard drive you will have trouble filling this baby up. (105 CD albums and counting) It comes complete with music management software which is a simple click and drag system. A normal CD usually takes about 5-10 mins to load to your pc and then to the Treo.
Also included is a leather look wallet in case you are a butter fingers (It won't take kind to being dropped on the floor).
Soundwise, brilliant, but you have to get rid of the cheap supplied headphones & obtain a decent pair.(the review would have been a 5 if decent phones were included).
Over all it can't be faulted. I have only had my Treo a month and I can't do without it.
