Windows is actually not too bad. I'm running Windows 8 on my Retina MBP in high-DPI mode, and it looks crisp and most apps degrade gracefully (some look absurdly small, but that's rarer). Admittedly, this isn't something that could happen today. But Intel's IGP are the low end. In a few years, they'll be everywhere. It's difficult to argue that something that requires a modern integrated graphics chip is anything too demanding, when you look at how far ahead dedicated chips are.
