Definitely much better a solution than Boot Camp.
I don't know about that. Sure, for the user under most circumstances, say, using one Windows app, it would be a bother to reboot. But, doesn't this mean there isn't as much separation between the two, like partitions and worse, what can infiltrate your computer via holes in Windows? I'm not sure about viruses getting in and moving to OS X (seems like getting in is just one part of the difficulty of breaching OS X), but somehow I can't see Windows being hit by its own errors and foreign maladies and not having some sort of effect on OS X.
One more thing...dual boot is plenty to persuade people afraid to let go of Windows to switch. Having Windows within OS X is better in the sense that you are primarily running OS X, and Windows can count sort of like another app, meaning that it by nature would be one of many, compared to OS X, which cannot be missed. But, then it becomes a different picture for many people. People that are rather disillusioned with Windows but afraid to let go in favor of Macs could easily favor a 2-in-1 solution like Apple proposes, and then choose what works for them, and abandon the other. Win within OS X is better for those that are somewhat convinced they need a couple of apps that are Windows only. In other words, for many people persuaded by Boot Camp to switch, the reality will be that they'll quickly find what they need on the Mac and not boot back. Others will want to boot every so often into Windows. Very few will boot every day, back and forth...unless it's at the office vs at home - but even then, if OS X can do it (Office, iWork, to Mail, iCal), don't expect them to boot back and forth for long.
Then there are those that aren't simply trying out if they will be OK on a Mac - those that know the Mac lacks some Windows software they need. These people will have to buy third party Win within OS X software to be satisfied. But I would be willing to bet Apple will never sell such software - it'd be better to start working on or attracting developers for new apps to beat the apps you need in Windows.
