Windows According to at least one blogger, Microsoft should abandon Vista before it's too late. It would appear he's not alone in this opinion, as Microsoft has begun allowing users to downgrade back to XP. Amongst the reasons? Poor sales figures and shoddy Vista "Extras".

Backwards compatibility is sacred at MS. There's an entire Shim database inside XP and Vista devoted to recognizing legacy apps which rely on undocumented behaviors and maintaining their performance.

A Unix-based OS with a truly divided security model doesn't play well with that. The graphics kernel in Windows is tightly integrated into the OS kernel, which is verboten in Unix-based systems. This is the bane of Cedega, which has to be continually patched app by app for compatibility.

XP could, as you suggested, have to be run in a sandbox, but they remember what happened to OS/2 when it offered Windows compatibility: no one had an incentive to develop for OS/2. Apple could have implemented XP compatibility when the Intel switch occured (they have legal access to the entire XP API), but they stayed out of that issue entirely.
