I just picked up my first ever Mac about four weeks ago, and it happens to be a Macbook pro unibody and I absolutely love it!!!
A little background: Many years ago I laughed and scoffed at Apple's and Apple owners and was a die-hard Windows user. However, somewhere along the way, perhaps indicative of growing old and impatient, I just want my computer to work and not have to futz with countless settings and drivers. That is not to say that I'm not quite capable of setting up any computer software combination, I'm 3 classes away from a Computer Science degree but I went to law school instead, but I digress, I've owned countless PC laptops and setup numerous networks for friends and family, as such I consider myself quite computer savvy.
As my laptop from law school started becoming slower and slower I took a look at all the options out there: including Apple since I've had such a fantastic experience with my iPhone over my old Windows Mobile phones. Moreover, our office recently acquired some Macs (we use them to redact police videos for trial) and I've really enjoyed the slick OS X experience with nary a crash.
After a few visits to the Apple store, I finally pulled the trigger and bought a 15" MBP. I can categorical state that this has been my best purchase EVER it's a rock solid laptop that is quite, stable, fast, looks great, and is easy to carry. Honestly the only problem I've had was a random Microsoft Office crash about two weeks ago.
Sorry to have gone rambling, but the short of it is that the MBP unibody is a fantastic laptop worth every penny.
