Hello skinee,
Up until a few months ago, I always used dell laptops with windows for personal use - then I got a MacBook Pro 2.3 GHz and have been really impressed. I use Linux at work (our main integrated navigation systems use it) and that too has some great advantages over windows.... But I'm not going to start blasting windows, it does it's job well.
In terms of running reefmaster, I got parallels so I could run it on the MacBook and it has not let me down. I have 1 copy of rm on my old dell and 1 on the MacBook parallels - admittedly the dell is about 5 years old, but the screen resolution and speed of the MacBook is very, very impressive when comparing. It renders 3d imagery from multiple track lines in seconds and I've been blown away with the final picture quality.
I'm using parallels 9 (haven't upgraded to OS X Yosemite, so haven't needed to upgrade to par 10, so I can't say if rm will have any problems with parallels 10, but I wouldn't have thought so). I'm also using windows 7 64bit.
Let me know if you want any more info about the MacBook Pro specs I'm using and I'll post the full system info to you. As I wrote, I'm really pleased with its performance and it copes with all the number crunching rm does with not so much as a yawn!
