If you don't miss all those thousands of mini-apps form Apples Appstore, like a phone you can hack all you want and are interested in a pocket-sized computer, I'd say buy a N900. You dont even have to be that technical person (some brains required) since you always (at least I have) get help from here. And then my personal opinion: I like this phone and haven't regretted buying it a single minute, so if you fit in the description above, I say go fot it!
