The thing I'll be interested to see is more what type of software support this will have in reality. Benchmarks might be good, but if it has the same issues Wine has (you have to look up which versions are compatible and change these settings and download these .net runtimes or whatever to get one app to work) then it really just isn't worth it. I have a Windows virtual machine and I can run any EXE I need to on it, which isn't many, usually just for testing Windows applications I need to test out. The thing that is most annoying for me isn't necessarily performance, just the fact I need to change Wine settings for every app I install. I really hope this takes off, but I also hope it is better than Wine not just in performance, but also in simplicity.
