GMail Drive shell extension (Software)
Every body is watching Google so closely, they got such a huge following. So many programmers are just thinking how can I leverage Google's software and API. Just around GMail, I find little things here and there that are pretty interesting. This Gmail as a v-drive is very interesting. I also use in Firefox an extension that checks my account every now and then so that I don't need to log, and run the risk of them deactivating my account because I don't use it much... Now that maps.google.com is out, how many more innovations are going to come out of such clever hack, Google has outdone themselves.
