Among my coworkers there's often the idea that Microsoft should have made the "no-longer-Metro" interface an add-on. Maybe it could be even installed on Windows 7... It seems to me that if Apple launches an "iOS as an app" for OS X, that allows people to run iPad applications in a sandbox and/or virtual machine alongside Mac applications, it would be a great thing.
