I don't think you'll be alone. With the retina MacBook Pros, Apple really is throwing down the gauntlet here.
And not just because of their advantage in hardware; Windows is notoriously hard to program for in a resolution independent way, and the first double resolution laptop displays are going to cause early adopters no end of pain. Even if Windows 8 brings APIs to fix it, the long tail of apps are not going to be updated any time soon.
I expect this to be an unusually large and concrete reason for everyday people to choose a Mac laptop for the next few years. Side by side, Macs will look amazing. Looked at a 3GS recently? Eww.
Of course, this is assuming OS X has resolution independence nailed; though I'd be amazed if they shipped this if that wasn't the case.

OK, so I set my DPI to 200% to check, and I found errors in every app I tried (list below), except for Dropbox, and MonoDevelop. Mostly the errors involve not everything scaling up; certain images or pieces of text will be too small.
That said, it was all purely visual stuff, and the errors were more subtle than I was expecting, so maybe my prediction was a little strong. Though if you track off the beaten path, I'm sure it gets worse - that VB6 App you use to track warehouse supplies may be completely broken.
