Will installing WIndows 2000 Professional over Windows ME allow me to use all of the apps and games that Windows ME has? Is there a tradeoff by going w/ the stable Win2k vs WinME, if so what is it? >>
In my professional opinion, there are no tradeoffs.
It's what YOU need from your OS.
Bottom line: both are windows - they feel very much the same. WinME is a little more cutting edge, but it comes with tons of problems. It crashes more than a crack addict driving a Ferrari, and it's more fickety than a manic depressive scitzo.
Windows 2000 is very stable *for Windows*. It has a nice interface, and is compatable with most software (and hardware, if you have up-to-date stuff). You'll find that some things in Windows 2000 are more complicated than they should be (system stuff, mostly) and if you're not used to NT you'll have a little of a learning curve.
I'd put my two cents on Windows 2000 for whatever you need, but if you are a heavy gamer and that's it, go with Windows 98 SE - it's much more stable than Windows ME.
Ateast, that's what /me thinks.
