Why I use a MacBook for the Web Designing?

I have used Windows OS for a long time and now days I am using MacBook to design websites and I think that it is a right choice and I am impressed by the speed and User Interface of Mac OS and it actually affects my speed too. I have realised that I am designing and learning better things with the faster speed. I am happy with the performance of my MacBook. Let me know what you think about these Operating System. Share your thoughts about MacOS and WinOS. I'll be writing a comparison of these Operating Systems on my blog shortly. Thanks!
