Google. A web based mail service. Financed by contextual ads. Free of charge. One gigabyte of mail storage. Keyworded categorisation. Built in exportation mechanism to other services, would you want to change over. Sadly no Safari support.
Brought public March 31, press release April 1, speculated about as an April fools joke - It's not. Sure the press release is in the spirit of the day, but the actual service is real. It's being beta tested for the moment. And it's a darn better deal than Hotmail, Yahoo! mail or any other free email service around.
