Since he asked what it was GOOD for, and not just what it does, I'm going to analyze BurnItDwn's post...
you can use openoffice for all your productivity work (or if you are one of those MS office is better type of people, you can install WINE and then use MS Office)
You can use openoffice on windows, too. Installing office under Wine as an alternative to using Office in windows is retarded.
you can use vi, pico, or emacs for all your programming/coding/scripting etc
Yep, this is a good use for linux
use Mozilla Firebird for browsing the web
Same as windows
There are plently of decent IRC clients for windows, too. I don't see linux as having an advantage here.
I'd actually say windows has the upper hand in FTP clients.
Proftpd or WUFTPd for FTP server
I prefer the command line linux ftp servers to things like Serv-U and WARftpd. Score one for linux.
Apache for webserver (with either PGsql or mysql)
Same on windows, although Apache is supposed to be more stable for unix than win32.
iptables so you can set it up as your router if you want to
True, but IPtables is a bitch to set up. If you really want to, though, then yeah, linux will work well for that.
The Gimp for photo editing (IMO just as good as photoshop for most things ... I like both though as Gimp can do some things better, and photoshop does some things better)
The Gimp is NOT jsut as good as photoshop for most things. If the Gimp was just as good as photoshop, graphic artists would use it. It doesn't even support CMYK color.
for the people that thing solitare and minesweeper are cool KDE and Gnome both come with a bunch of crappy little games, though none are quite as bad as minesweeper.
Heh, those little games suck on boh windows an linux
😉
you can use KIT or GAIM to access the AIM network and use it for Instant Messaging
Not any better than chatting on windows, though.
XMMS will play mp3s and avis and mpegs ... you should be able to find most codecs for linux on the web
You can do that stuff equally as well in windows.
use Samba for file sharing (and printer sharing if you want) ...
Samba is cool if you're sharing files across machines with different OSes, but if it's as an alternative to an all windows network, I don't see it as an advantage.
