To chime in here.
We just had our second, in two years, full datacenter outage of ALL production systems. This was caused by one of our VMware hosts locking all of the datastores causing the other VMware hosts to get locked out and all systems grinding to a halt. Two years ago VMware stated it was a bug in their 4.5 code. We're now running 5.5 u1 and the bug is supposed to be fixed, however it caused a 12 hour companywide outage again. The only way to fix it was to shut down all VMware hosts, unpresent all storage, bring the hosts back online, and then present storage again. VMware cannot explain why this has happened. Right now we're starting to run Hyper-V server in our remote sites to replace standalone ESX boxes and it's working out. We're going to start testing Hyper-V in our development environment to see if we have similar issues. I like the idea of being able to run with CSVs or over SMB as options for guests. Plus virtualized Fiber HBAs for guest clusters is something we are having major issues with in VMware that looks to work better in Hyper-V, on paper at least.

And using the bare Windows Hypervisor greatly reduces the surface area of threats, if you feel that it is too high otherwise. (Not running other roles on the Hyper-V box will also reduce the surface area.)

No.... It still can get a virus/worm which could cripple your hypervisor and render your VM's useless... vSphere costs a heck of a lot more but it's been a pretty reliable system which I haven't had to patch much at all over the past 2 years.
