If you don't want to work on the old bike, fine. Your choice. But you might find that working on bikes is a relaxing hobby - especially if you have a bike to work on where it doesn't matter so much if you screw something up. If I was you (and I know I'm not) I'd keep the old bike as a project bike and start fixing it up slowly, at your own pace. Each time you come up against a job you don't feel equipped to do, take your time, do some research, and dive in. It's really not that hard. Eventually you may get a nice bike you'll be proud of, and you'll become competant to fix things that may go wrong on your new bike. I've bought old, in-need-of-repair project bikes for the fun of fixing them up, even when I didn't have anyone in mind for them. I find that if I purchase parts bit by bit I don't feel the drain on my budget much - especially if I use Ebay with patience.
Anyway, I like the new bike. I'm a Specialized fan myself. My family has three Rockhoppers, a Stumpjumper, a kids' Hard Rock, and an Allez.
