As someone who's used a shiny new Macbook Pro with Retina display for just under a year now, I absolutely love it.
I bought my wife a 13" MBP in 2011 and she enjoys it (does photography and video editing with it), I currently have 3 laptops for my personal use, a 2011 Lenovo T520 15", a 2012 Lenovo T430 14" and the 15" MBP Retina.
All 3 are work supplied machines, I got the T520 and like it quite a bit, but rarely use it anymore, got the fancy pants Retina MBP when I started a new position and the boss asked what I wanted to do my job with, I went for what was basically the best laptop available at the time and he said ok. Then my company outsourced us late last year and I got the T530.
I have used probably a half dozen Thinkpad's, starting with an IBM T43, then moving to a T60, the T61, then T510 before getting the T520 and T430 (again, all supplied by my employer, yes I am a spoiled fancy pants who gets new stuff too often from my job).
I use the MBP Retina pretty much exclusively, if I need Windows based stuff I RDP to my desktop at work and work through that.
With that said, if I moved away from my job would I dare drop 1500-2000 on the laptop I type this on? Absolutely not, it's an amazing machine, and just like if someone offered to let me drive a BMW every day I would enjoy it and miss it when it was gone, but not worth the face punch I should get if I were to buy one myself.
