I just started setting up my PC as dual boot Win98se and Win2k. I'm about halfway through it (98 installed) and I'm wondering if I even need 98 anymore. So my question is:

Other than gaming, what applications have cause incompatibility problems on Win2k?

Some of the applications I will be running are
MS Visual Studios 6.0
Adobe Photoshop
Macromedia Flash
(Whatever other art programs my sister would use)
AIM
