As for the problem with it being freeware, my entire desktop is nothing but freeware, from the OS up. Given the utility and security it provides me I fail to find that as a charge against it. Yes, it's probably not a really good idea to take the top hit on Google for something like this, but I also figure that if you're going to take the time to implement sandboxing, it would make a wee bit of sense to also take the time to figure out if it is a good solution for you.
As for getting the VM solution by those who created the OS, that's a pretty iffy statement. As far as security goes, Microsoft, as a vendor doesn't exactly have a sterling history. Of the VM solutions out there, I personally like VMware better, because I like the feature set and stability. I don't have any particular animus towards virtualPC, but last time I took the time to look at it, it was several years behind VMware. That may not be true now, as microsoft has a history of continuing to slog along with inferior products until they finally get it right.
Having choice in the marketplace for different solutions is a Good Thing IMO, because not every solution will fit every need. Sometimes it takes time and effort to even determine what your needs are, and a little trial and error to discover what fills them. I'm just glad we have options and don't have to take just whatever it is that a single vendor decides to make available. Do you recall what happened with Internet Explorer once Microsoft had driven Netscape out of business? They sat on their asses for years while the rest of the world who wanted a browser that actually worked and had things like tabs passed them by. I still think IE is a steaming pile of crap that has market space primarily because of the inertia provided by the lazy and clueless who don't even know about the alternatives. That's my own personal opinion though, given my personal experiences with it. YMMV.
