ive had one since February, i've never had any problems with it, and the apps that i have downloaded have served a good purpose. there are tons of apps, and yes, some are completely worthless, but if you use discretion to chose what you think you need, you wont end up with a worthless app. my apps, un general, 3 pages worth, take up less than 700mb. i do however have 4.5 gigs of my home selection of music on it, and about 1.5 gigs of pictures. having alot on it will slow it down, but not much.
