Of course, if you already have your PS3 (like your comment suggests you do), you can still do so. Have fun!

I would tend to agree with this evaluation. I have a semi old computer (P3 733) and use Yahoo as my primary webmail, the new interface is noticably slower, taking a few seconds to load versus the nearly instant loading of the old one. The fact that Yahoo also generally has animated flash ads running means leaving the window open isn't that great an option either. In contrast, gmail seems to load considerably faster, seems more responsive to my clicks, and has no flash ads.

Inertia is what's keeping me with Yahoo as my primary webmail, but if I had a fresh start, I'd probably go with gmail.
