I think it is worth it. But it depends on what you sacrifice for it.
This is by far the best computer I've ever had : amazing screen quality, amazing battery life and every Apple's neat improvements on usability.
Mac OS X is a great OS which comes loaded with a lot of high quality apps.
You can count on superior customer service too (if you have access to a genius bar)
Do you need a Macbook pro ? Probably not. Would you enjoy having one ? Definitely.
