At the moment, the 2.3 GHz "Retina" MBP is $2199 with 8GB of RAM and a 256GB SSD (bare-minimum specs)
A "non-retina" 15" MBP with bare-minimum specs (4GB RAM, 2.3 GHz processor) but with the same 256GB SSD is $2299.
At the other end of the spectrum, a 2.7GHz "retina" with 16GB of RAM and the 768GB SSD is $3299. A worse "non-retina" laptop (only 8GB of RAM, since that's all Apple will let you put in those, and only 512GB SSD for the same reason) is $3349.
Oh, and for the non-retina machine I assumed you get the cheaper 1440x900 screen. Of course the "retina" machine can be easily run at 1680x1050 if desired.
If you don't want/need the SSD, the numbers look quite different, of course.
That said, I'm not sure what you think is "unsupported" by Office and VirtualBox. They won't run at 2880x1800, but they'll run no worse than they would on a 1440x900 15" mbp.
And when I say unsupported, I mean that they look crappy because they don't have Retina support.

Well, more precisely they look just like they do a non-retina mbp. Which is worse than Safari or Terminal on the retina mbp, of course, but not any worse than you'd deal with if you got the non-retina machine. Or am I missing something?
I guess if/when I ran iPhoto it might look jarring. If I weren't running it full-screen on its own desktop, of course.
All of which is to say that it really depends on individual usage patterns.
I lugged a 2011 MBP 15 laptop around a lot. Now I lug a 2012 rMBP around, big difference in weight. Plus, I can jack the screen resolution up to 1900x1200 or whatever when I need it.
Of course the non retina apps like firefox, thunderbird, opera show up exceedingly fuzzy. I'd like to continue to use them but they're just hideous and i have to revert to Safari/Chrome
