I just bought my first Mac (and Intel iMac) about 4 months ago. When I bought it, I immediately purchased a copy of Windows to install on it - fearing compatibility issues with my other PCs. It took me about 3 weeks to really get comfortable using Mac OS X, and to become an "fluent" with it as I am with Windows - but now, I've realized that I don't even use Windows anymore! Has anyone else shared this experience?
