We recently (read: since February) started migrating VMWare to Hyper-V with some great success. Since then, I've become a bit of a fan of Hyper-V in it's current form. Hope to get excited about this one as well!
One of my current project is deploying Hyper-V hosts to our branch offices and looking forward to see new improvements with enhanced Hyper-V Replica with WS2012 R2.
excellent session the best I have seen today, kept me captivated until the end
