What's happening? Why do you need to reboot it? I'm not saying it's perfect, or I cannot make it to crash if I work on it ( ), but IMHO it is somewhat more stable than either SP1 or SP2.Hmmm... Macs may crash, but they crash a mere fraction of the time that this thing does. I have to reboot my SP3 at least once a day, and frankly it's getting old.
