Now that I'm home, I can add more, all the ones I use, in fact:
WinRAR: My archiving software of choice. Dropbox: Automatic backup in the cloud. Use my Referral link, we'll both get more space! Google Talk: Takes GMail's chat feature out of the chat window. Skype: For phoning home for free! FlashGet: Download manager. Inkskape: Vector graphics drawing program, useful for the odd diagram or doodle. AShampoo: My preferred burning software. PowerISO: For easy use of image files. LastFM: Keeps track of my listening habits. VLC: Least hassles with codecs ever. Winamp: I still haven't found a simple replacement that just works. Calibre: Library app to keep track of the gf's billions of ebooks. Sumatra: PDF reader to replace Adobe's reader. ESET Smart Security: The only av & firewall I trust. Peerblock: Keeps out unscrupulous IP's.
