I absolutely loathe Y! Mail's new interface. It's suppose to resemble Outlook and Oddpost (Y! acquired them) folks have spent a lot of time copying it. Problem is that Outlook's UI is not that great to begin with. All that clicking and dragging and split-pane views are so damn annoying and slow.

Gmail has Y! Mail beat even with this storage system.

I also don't trust Y! as much as I trust Google... that China incident just turned me off Y!.

Google already has them beat: http://www.flickr.com/photos/strategicpause/434015378/in/set-72157600026714867/

Is this really 'leapfrogging' reliable services that offer 2+gigs for space? I don't know about other people's email usages, but gmail has a ceiling I will not be sneaking up on anytime soon. I guess it is nice to know that you do have unlimited space, but I don't think this announcement is nearly as cool as gmail's 1 gig.

PR move, just like "unlimited internet". The architecture doesn't support unlimited anything, but like everyone else I have, what, 100MB in there, tops? So declare victory and go home. Doesn't cost them a thing except some config work by the Mail team.

Seems like such a "me too" move at this point. They should be trying to offer something uniquely great that Google hasn't thought of.

How can they detect abuse without violating your privacy?

Probably based on usage patterns.
