The Nokia N70 is known for being a bit slow... but, it's a pretty good smartphone.
I've had two Motos. My last was a V635. Crash, crash, crash, all the




ing time.
I had a Nokia N73 briefly. It never crashed but the screen started to fill up with dust (from the inside) within weeks and that pissed me off.
My present phone is a Nokia N95, and it never crashes.
Which is saying something because I'm always installing new software and playing lots of processor intensive games on it (like Quake and the few N-Gage titles available), and I haven't turned it off in a month.
(Come to think of it, if you don't power your Moto off and on very much, start doing that now. If there are memory leaks, long periods of uptime will result in all available memory trickling away, until *boom*. Goodbye and hello again Moto.)
