I've watched the free training on Hyper-V that Microsoft made available, and had some discussions with Microsoft, but I have yet to actually load it.
Here's my impressions from the training and discussions I've had:
I think that it won't touch Vmware ESX in the enterprise space where high availibility is essential, until they work out their own version of VMotion. Their quick migration is good, but it's tough to stack up against VMotion for sensitive applications. With Vmotion, we tend to lose no more than one ping on a migration from one host to another.
Where I am taking a serious look at Hyper-V is for things that won't fit in our ESX environment. For example - we have one server that I can't migrate to our ESX environment because it has a hardcoded IP address in the application, and that subnet doesn't exist on the switches connected to our ESX servers. It is also a 6 year old server.  So Hyper-V would be perfect for this, because I could put it on low end available server and the licensing cost and aggravation to my network team would be minimal. I was considering ESX3i for the same thing now that it's free, and then noticed that the ESX3i Hypervisor is extremely limited when it comes to what hardware it will run under.
now on the other side.. I've seen one thing on the Hyper-V side that I hadn't seen on the VMware side that I find very interesting, and that is dynamic processor allocation. Currently in Vmware ESX 3.5 the only thing I can add or change on a running virtual machine are new disks or what subnet the network adapter is pointed. In Hyper-V on 2008 it appears that the only thing you can't change on the fly is the amount of memory reserved for the VM. Hyper-V also seems to run on a much wider variety of hardware.
Thanks for reading my blog - I really enjoy doing it.
oh and the link if you want to do the MS free training on Hyper-V is :

I thought it was really well done, especially considering the price. A bit dry though when compared to the episode 65 here.
