In this day and age, a $3000 computer is INSANE!
Especially when you can buy a $399 laptop at BBY, Newegg, or Amazon that does what MOST people do with them:
Internet
Email
Social Networking
Media (Music and movies)
I know that is an unfair statement because Apple doesn't make CHEAP computers. When you price out a GOOD PC (Samsung Series 9, Asus), it is about the same price of the MBP's anyways
I just upgraded my 3 year old i7 1.6 Sony VIAO with Windows 8, and all I can say is I LOVE IT. Best seen to date. Many new features, and I had been running the public release Beta for the last 2 months.
I also just purchased the new cMBP 2 weeks ago. And I love it. Last Mac was back in 1990 with the Mac IIc.
Sure I like the retina screen, but the cost of admission for what I wanted (16G Ram and 512 SSD) was way to much, and money for me was not an issue.
The cMBP for $1799 (still a little high compared to PC's), but I told my self it was worth the extra premium, and the real reason I bought the Mac was to have full integration with my iphone and iPad.
I have already ordered 16G ram from OWC for $100 and plan on an SSD during the holiday season, however, I am quite happy with the performance of the 5400PM 500G drive that came standard with the cMBP.
Probably will pick up a 256G Samsung SSD for the SOny and just see how it is, faster booting to me is no big deal, I can wait the extra 15 sec. But I, like most love new technology.
ANd if it is as GOOD as most say, I'll hunt for a Samsung 840 Pro 512, when the prices drop a bit ($400-$500).
Anyways, go luck with your decision.
Oh, and the lack of upgradability of the rMBP was what I did not like. To be STUCK with what I buy today for the next 4-5 years.
My Sony, 3.5 years old i7 with Bluray and 1080P; Upgraded the ram and will add SSD this winter. Things I like to do anyway.
