Ubuntu vs Windows.
I've used both Windows and Ubuntu and they both need a lot of familiarization. However Windows disappoints me. I feel all the effort goes into protecting Microsoft's income streams as opposed to providing a product that customers can use and upgrade with all their other programs.
I'd rather have to mess around with a program that cost me zilch than one that is just as dysfunctional and it's cost me dearly: One I have to uninstall from my old machine to use it on another. One that will not run the software I use for my accounts or gaming software I bought.
Sorry Microsoft with your Windows in your various guises. I guess Fear of the Unkown is what's keeping you in business.
