What software, websites, devices are most useful to you?

Here are the ones that I wouldn’t want to be without.

Twitter.com – Keeps me in touch with friends and family. (What is it?)
Digg.com – Voted on news.
Digsby – Multi Protocol Instant Message Client with social networking apps (Twitter, Facebook, etc…)
iPhone – Syncs my podcast &  music and runs all sorts of useful apps.
Firefox – My choice in web broswer. Featured packed & extension support.
Flickr – Easily lets me share photos and photo blog.
uTorrent – Best torrent client out there for getting things from “spaces.”
