The main reason is that I purchased a Lexmark X5250 without control if there were Linux drivers, so I must use it from Windows.
The second reason is that I have very few time to manage my computer, so my Linux distros have a confused set-up, so sometimes is simpler, expecially for my father, to use Windows.

However, I would like to set up my Linux distro(s) so I really don't need XP at all, but for make such a thing I still need some skills and time

Well, lets see:
I need windoze for Auturun max, Quicken, Seagate hard drive software, and my camera because I still haven't figured out how to get the photos off my camera in suse 10.0.
So:
I still dual boot.

I don't dual boot but have two separate PCs, one Windows and one Linux. I got my Windows box for nothing and it's my kids that use it most of the time for games. I don't need Windows and rarely use it, although I would definitely miss Photoshop if it wasn't available, even though Gimp is a great app. My future plan is to replace the Windows box with an iMac and just run OSX and Linux at home. I must admit, even though OpenOffice is a great package, I still prefer to use MS Office, in particular MS Word.

Cheers

Primarily stuck with Windows because of games.

Dune (Yes, the first one, never got to finish it)
Star Command
Banzai Bug
Populous: The Beginning
Age Of Wonders
Baldur's Gate II - Shadows of Amn
American McGee's Alice
Unreal Tournament G.O.T.Y. + Custom skins & models
Ragnarok Online (MMORPG)
GunZ: The Duel (MMORPG)

I could name more but i'm not at home right now. Most of my collection needs arcane tricks just to get running on Windows XP already, I can't imagine how to do it on Linux yet.

Depends on how you define more advanced. I haven't yet found anything in MS office that I can't do in some app in Linux

MS FlightSim, Canon pixma ip4100(no linux drivers), Boson NetSim, and the Juniper Networks VPN client(Ironically, to talk to Sun boxen).
OTT, it's CentOS4.

>> "Dual Booters out there -- What do you still run on Windows ..."

there might be quite a number of reasons - how ever valid they are - for people to still having windows at homes or workplace ... but remember ... the ultimate goals - we need some goals downhere sometimes - are to not running windows at all , not even replacing(this is just a word) them with some better systems ...

it could be hard but take them as a personal private challanges with some kind of impossibilities which are somehow obligational extensively ...

and ... windows at homes and schools are definitely not obligational ... i mean ... at least the challenges are not as "deadly" as in the coporate world or of it kind ...

who knows ... we might be seeing people adapting and be educated themselves to a somewhat healthier + more productive lifestyles during the process of the challenge ...

Don't count me anymore.. i just deleted windowz... I quit playing games that don't run under Linux with wine... cherrs

In answer to the original question:

My partner has a Slackware 10.2 and Windows 98SE dual-boot machine. The Win98 is retained for Quick Books, an accounting programme, and for a DOS version of Bridge, the peg and colour version of Master Mind, and a couple of CD-based games, such as CSI, Who wants to be a millionaire and Age of Empires.

Any suggestions on GNU/Linux replacements for these that would run on Slackware using KDE not GNOME or it's libraries?

Cheers

Games and Google Earth

I use WinXP/SuSe 9.3. I am still using Windows for multimedia purposes. This is the only problem keeping me from switching to linux entirely. Every distribution that I have tried has the same problem. Mainly codecs for viewing streams.

i keep windows just for my lexmark printer and thats it.

Multimedia is not a problem. Just use MPlayer with w32codecs-all and kmplayer installed and you have full mm support. You can also use IE and windows media player 6.4 and/or quicktime with wine.

Simple, windows is for gaming and websites that need shockwave. (I also use it for Winamp because there is not music visualization for linux that could possibly compete with milkdrop.. And performace sucks under WINE/Cedega.)
Games I don't use windows for:
Doom 1-3
Quake 1-4
Unreal Tournament ****
Any game that runs okay under cedega.

I use linux for school, work, programming, fun, the gimp suits my image processing needs, and anything else that I can do without using windows because I've used alpha software more reliable than windows xp.
