what all will linux run i never tryed got to keep easy for kids where can get from to try it 10 to 1 is my kids age got 6 of them..lol
Well Its like most other operating systems in that it will run whatever is made for it. I don't have a list with me but they have a linux version of almost every program available or atleast a comparable product made by a 3rd party.It would be faster to make a list of what DOESN'T run on it. In terms of looks you can customize it to look a lot like windows if that suits your fancy. For web browsers and general use stuff (browsing, flash/java games, word processing) its exactly the same.
It does take some trouble shooting if things don't work right off the bat (say you are having trouble installing a program) though they have it very well documented.
It might take you a little while to get accustomed to it since you are so used to windows but I highly recommend trying it out before dropping over half a grand on windows.
