If there is one feature that would make me switch to Windows Live Mail, this would be it. Spell Check As You Type! I admit I am very bad in spelling. I always liked how Word would underline my mistakes with the red squiggles. Now Windows Live Mail (the name Hotmail is cooler IMHO) team claim to have done it without having to install anything.
Pretty cool. They even have a cool video showing it off. They also claim Windows Live Mail to be the first web mail service to have pulled it off. I don’t know about web mail service but Emil has a PHP version of such a spellchecker for quite some time.
Anyway I can not wait to get a invite to the Windows Live Mail beta to try it out. Hey Scoble can you get me an invite?
