I don't regret it at all. It's a great device. I haven't had my macbook with me since Christmas. That reminds me.. God damn that reminds me.. The battery is going to be so dead in my macbook I've had it repaired twice already cause I forget it on standby and it runs out of juice and won't recharge anymore, and it's been like 1.5 months now.. god damnit.
Well they should accept it on warranty still, since Apple agreed it's their fault, even though the original warranty has already run out.

Oh yeah back to topic. Don't regret it at all. Don't see why Maemo 6 wouldn't work on N900 in the future, maybe few features have to be stripped, but should mostly work? Don't mind putting a few more bucks on my N900 if we have to pay for M6 either. It's just that good a phone/device.
