I have three Yahoo!, two Gmail and zero hotmail accounts. I used to have one hotmail and one MSN account long back..but they do not exists any more due to in-activity.
I use Yahoo! mail everyday and it is my all time favorite online mail client at present; and desperately waiting for the new beta version to explore more features. Last week I asked Yahoo! mail team to send me access to the new beta version, and will get one very soon.
Anyway, coming to the point, Google Gmail sucks!. Want to know more, why it does ? check the following links:
