The Google I/O team has out done themselves. They decided to figure out what E-mail would be like if it were invented today. Thus Google Wave, a clever mix of E-mail, IM, Photosharing, EtC.
Their spell checker, named "Spelly" is a server side app that takes the context of the misspelled word, and corrects it accordingly. I.E. "Icland is and Icland." becomes "Iceland is an island."
Their bots, named "Tweety" and "Bloggy" will automatically post you Wave as a post on your Twitter or Blog, respectivly.
In a work enviroment, if there is a document that needs done by a team, one person makes a draft, sends it out, everybody edits it, send it back, it gets recompiled, and they do it again and again until it's done in a few weeks. In wave, the draft cna be posted, and then EVERYBODY on the team can edit it at the same time, talk about why they are doing what they are doing, and continue the editing REALTIME. No more recompiling, no more waiting for the transit.
For fun and work, Google Wave will revolutionize the idea of Email.
GOOGLE I/O, FINISH AND GET IT OUT NOW!!!
