Let's be clear, I'm still using OSX at work, mostly because there's no need to change there these days. The computer is already there, so why change?
For the past 8 or 9 years I've been using as my main computer a macbookpro. First gen I bought was awesome, lasted for years. Upgraded it with some more RAM, and then I even removed the DVD player (remember those?) and shoved a SSD and the computer was great.
