My current laptop is a macbook pro; absolutely no problems at all. I use it all the time and run windows 7 on it as well. You get Apple and Windows, plus the best quality out there.
My dad has a Sony vaio, which is okay, but the wifi went out. I had an HP before the mac and that was good but the screen went out once under warranty, and after 2.5 years it really started to fall apart (hopefully the Mac won't do this). Had a Compaq before the hp and that was pure trash.
