Believe me gamahiro, I would love to ditch windows altogether but I have three reasons that always stop me from doing it:
1- I really, really, really need One Note. There's just no way around it, it's a beautifully built and very useful program. You wouldn't even think it was made by Microsoft. The open source alternatives just don't cut it, they have lots of functionality to deal with code, console integration and such, but the developers don't even think about the users that are not constantly coding. For example, while One Note properly supports tablet input, most of the alternatives don't even have a pen function. And it's not something hard to do either, just grab some open source paint code or something.
edit: I've tried whine, runs like shit.
2- I'm a student and I'm not rich. That means that for the time being I'm stuck with my laptop. And, look at my luck, of all the graphics cards in the world, X.org doesn't support mine, and the manufacturer refuses to release their linux drivers. This means maximum resolution is 800x600 with horrible performance, and I just can't have that.
3- Linux is hard work. Even with ubuntu you have to know how to mess around with things, and I just don't know how to do it, and don't know how to start learning. The master's I'm taking is eventually going to make me learn how to fiddle around with it, but until now no luck..
