The "new" Yahoo! Mail (beta)

As a techie, as much as possible, I would like to be one of the early adapters, but sometimes, it gets the most out of me. IN the case of Yahoo! Mail (beta), well, yeah it's got a nice UI, but it's sloooooowwwwww! And most of the time, it hugs the resources of my web browser. Well, I guess that's what I get for trying out a BETA service. Nonetheless it's the only gripe that I have for the moment.
