Who said Windows wasn't stable?
Seriously, I've never had huge problems with the stability of Windows 3.1 on my laptop computer, even now without years of patches and updates the OS works just fine. ;)
The only problem I've got at the moment is my floppy drive which refuses to function. And that sucks big time. I cannot install any new driver, nor other software. So my plans for the weekend to re-install Windows for funsies are challanged by the hardware. Frankly, that's quite disappointing.
