Maybe the fonts appear "less crisp" to you, but to most of the rest of us here, those fonts are so blurry you get headache after 10 minutes. That makes the user interface UNUSABLE!
Many of us here are fully aware of Microsoft's reasons for doing this (they have been stated before), but that does not make those reasons valid.
Microsoft's corporate thinking on this matter is seriously and fundamentally deficient.
There is simply no excuse whatsoever for inflicting blurry text on customers who work in front of desktop monitors all day. Some posters here also have serious problems with blurry text on laptops with relatively high pixel densities.
It really beggars belief that Microsoft saw fit to do this. The whole issue smacks of internal corporate politics being played by an arrogant senior management that is seriously out of touch with customers.
We, the customers, demand the option to use RGB sub-pixel anti-aliasing in IE10 and Office 2013 on Windows 8.
