Since my ISP has partnered with Yahoo! (dating back years ago) to provide services like e-mail and hosting, we as customers usually get the best or second best that Yahoo! has to offer. That being said, I've never used their new e-mail service, but I've read a few reviews online saying that it's great. I'm also pretty sure that jitspoe is a die-hard Y!-mail user dating back 10 years.
