It's *still* a handset. The lifespan is 18 months. Or less. Much less right now since hardware in this space is changing very quickly, and especially in the maemo + hardware space since both are evolving very quickly. If you want a (possibly) longer-term supported device, waiting for whatever is after the n900 isn't a bad choice. Like the first iphone was never going to be able to be a 3g device, the n900 isn't ever going to be everything the next device is. Then again, that's always true. The G1 isn't the Nexus One, nor will it ever be. After 18 months, the G1 is looking pretty dated.
