Comment on Mail

Used this for a long time. Then I got sick of it maxing out my processor, the non-stop HD reads, and many many crashes.
Switched to Thunderbird. Haven't looked back.

That aside, it really is a VERY good email client. Easy to use, nice interface, and works with everything I've thrown at it. But it doesn't seem to be a good choice for a laptop because of its processor and HD activity if you let it run too long. In that case, switch to Thunderbird, or something else. It sits happily for weeks on end without a problem.
