Are there still apps for Windows 3 people would use on modern OS'? I'm under the impression you would run a VM if you really must, until/if when you make a transition.
I have one I'd love to use but it's no longer usable even under a VM. It's an audio mixing game called "No World Order" put out by Todd Rundgren back in 1993. It was a Windows 3.1 app, but remarkably worked up until I switched to Windows 7 64-bit. Even then, I could get it to work reasonably well with Windows XP in a VMware VM. Sound and graphics compatibility have never been a big priority for VMware, and the most recent VMware Workstation update seems to have broken the audio to a degree that I can't play the game anymore. I'm going to try VirtualBox at some point, but it's increasingly difficult to get a new Windows XP system up and running.
