That depends largely on what you do.<div><br></div><div>As I mentioned, I'm a developer using IBM tools, and Oracle. IBM's stuff is java based, and is horribly bloaty and memory hungry. When I'm testing and running the apps I'm writing, it's doing a lot of (database) I/O. When I'm coding them, it's doing a lot of filesystem I/O compiling and such.</div>
<div><br></div><div>Windows I/O is pretty bad to begin with, and that's exacerbated on a VM (and even more so when using a compressed NTFS filesystem, or using VirtualBox's "shared folders" functionality). So for me, there's a quite noticeable speed difference when Windows is in a VM, even when I give it a full 4G of RAM.</div>
<div><br></div><div>I'm not sure I get the "trust" issue; the problems I've seen on Windows have been almost exclusively "bad user behavior" which can be done equally on a VM or not, but undoubtedly my experiences and context are wildly different from yours, so do what works for you of course. =)</div>
<div><br></div><div>All that said I'm still amazed at the VM technology at all; no matter what's being run as guest or host. Everything mostly just works; I find it all quite amazing. Every day I find wonder at how far in the future I live now, and what fantastic things my son will see in his lifetime.</div>

<p>I know that I for one do not trust Windows for running on bare hardware. It is constrained to a VM on my system, under VirtualBox.</p>
<p>It works pretty well there. As best as I can tell, native speed. In truth, probably less, but not noticeably so.</p>
