Favorite Software? Haha, I got a lot... let me see:
1. Winamp - Obvious, but I got a lot of music in a lot of different formats... so I need it.
2. 7-zip - Best compression/decompression software available. Compresses files into .7z format also, which has better compression than .rar.
3. Textpad - Replaces notepad and wordpad easily, with soooo many more options. Try it before you say I don't need it, like I did.... and I still havn't un-installed it.
4. Fireworks MX 2004 - I like it better than Photoshop CS mainly because it integrates so well with Dreamweaver and offers everything that Photoshop offers...
5. mIRC - Where else would I get the cracks neccesary to run Fireworks and Dreamweaver
6. Openoffice.org - I'm cheap, and it works well.
7. Firefox + Thunderbird - Obvious.
8. XMPlay - Small as hell, lightweight music player. Plays virtual every audio file and music stream(exception of real audio, of course) known to man, and weighs in around 290 kbs (can anyone say flashdrive

) !
9. nLite - Allows you to make a "lighter" version of Windows XP. Basically, it allows you to get rid of whatever you don't need, like extra languages, services, and what not from the Window's Install CD, and than make a new Bootable windows install cd without those things you removed. Dropped the final install size for my computer by 500 mbs...
10. CD N' Go - Now obsolette, but the best ripper for ogg/mp3/mp4/etc. files I know of. Also has a really great ID3(or equivalent) editor.
11. Gaim - Best replacement for AIM... gotta love tabs.
12. Bit Torrent(BitTornado to be exact) - Obvious
13. Resource Hacker - Allows you to change the way your programs look... It's hard to explain, you really need to fiddle around with it to understand what it's capable of. I managed to remove the start button on my desktop with it
14. WS_FTP server - my ftp server.
Hmm, I'm sure there are more... can't think of them off the top of my head though.
