uhh.. well, since there's enough alternative shit, I can live without most programs. I mean, there are thousands of mail-programs. So who cares? But I like Opera's special features. aMSN would also be on my list, I think.. Let me take someone else's list..
Apple stuff: Nope
Imaging and animation:
Gimp
File Sharing: I don't do that
Burning programs: Don't do that either (well, haven't done that for a month or 2).
K3b maybe? But there are probably lots of alternatives
Browsers:
Opera 
Konqueror is also nice (and it is also a filebrowser)
Anti adware & spyware: Don't need that
Norton: Nope
IM:
aMSN
Extractors: Ark [couldn't find website]
Navigation: Nope
Skinning: Why would I need that? I don't need special programs just to change my toolbar a bit
Ram optimizor: is that any good?
FTP: I really like
gFTP, but it isn't anything special. It's like WS_FTP LE
Games:
not on my PC, Frozen-bubble!! Rocks!! but I really like my
NGC games
Editors: uhhh...
OpenOffice for school..
Kate as editor (not to write letters and stuff, I use OpenOffice for that
)
Mail:
KMail
Multimedia:
XMMS (WinAmp clone for Linux)
Edit: Added links+Mailers+Frozen-bubble in games+multimedia+added the following:
All are free (as in bear, and as in speech), except my NGC Games, and Opera (Opera has a little ad and isn't "free" as in speech).
