Microsoft puts a ton of work into keeping backwards compatibility. You can watch the YouTube Video[0] of someone upgrading through every Windows version (well, most?). OS X users have to figure out if they need that Intel or PPC binary, or maybe just the larger universal one and call it a day. Then there's not being able to run any of their older PPC-only apps once Apple removed Rosetta from OS X.
This hasn't been an issue for years. Since Rosetta was killed off in 2011 you really don't see any UB/PPC apps around.

Whoa, how is life in 2006?

I would like an example of the app that you absolutely want to run.

Usually MS fails at it. Upgrading to win 8 made me furious because apps stopped working. I still remember time when I had to dual-boot win 98 and xp in order to play pre-xp games.
The only case I have ever come across of an OS X app that depends on rosetta is one of my clients upgrading to a retina MacBook Pro 15" when she ran a decade old, macro heavy, film production bidding spreadsheet in Office X. Got Snow Leopard in a VM for her and she's on her merry way.

Old versions of Photoshop. Lots of stuff. I'm so glad that practically zero businesses run Macs because Apple really does suck at backwards compatibility- and as a business programmer, I'm just glad that I don't have to deal with all that. Maybe that's why businesses don't really use them? It probably has more to do with the hardware lock-in though honestly.
Making old business software run on current Windows is a breeze. My parents even ran their old DOS accounting package on Windows for their small business - all the way up through Windows XP and then they retired altogether.
