I am currently using a HP G60 laptop. Runs Windows 7 very well. I created a dual boot environment so I could install Windows 2008 R2 and to my pleasant surprise found Hyper-V runs on it. Need to enable virtualisation in the BIOS but apart from that slight hiccup it installs and works very well. Once I get the RTM version it will be time to finally abandon Virtual PC.
Also gives me a chance to play with James’ Hyper-V library.
