To me the storage is just one part of it. Hotmail is so UNuserfriendly compared to gMail that the increase in space no longer makes a difference to me. I haven't checked any of my 9 hotmail accounts since I got my one gMail. I guess someone else will be able to register soon.
LOL..Hotmail must be reading this thread, they increased the size of my mailbox less than an hour after posting here. Too little too late in my opinion
