I work with macs for 15 years now and if it was up to me i would say, go for mac

Its a combination of the rights software and an operating system which doesn't clutter up with all kind of startup items, dll's.
I am a developer of software and for my job i also need to work on a PC alot, i can confirm from experience that every 6 months you do need a complete install of your OS because its getting slower and slower if you don't keep your machine nice and tidy (that means, dont use the internet, dont install software and games on it, keep your desktop clean

) In comparison: my macbook pro runs for 2 years now without having to install everything over and on this macbook i run all kind of applications and test software also.
When my work is done, i simply close the lid and put it to sleep and i won't have to reboot for weeks.
The only downside of a macbook pro is you can buy 3 cheep pc laptops for the price it will cost you.
