Google Desktop Search
It's about time Google came up with something new. I was beginning to think we'd not heard anything from them for ages because they were all to busy stuffing their faces with fine cuisine, and relaxing in bean-bag chairs, to actually do anything.
It turns out not - instead, they've been working on Google Desktop, a tool to allow you to search the files on your own PC.
Much like Copernic's Desktop Search tool, this searches your contacts, emails, documents, web history, and much more.
It's still in beta, and only supports IE (boo, hiss, etc), but this looks like an interesting development on the desktop from our favourite search engine!
