They have to justify the extra price somehow... I don't blame them too much, odds are you are a "pro" user if you want/need Hyper-V. I really like Hyper-V (except the network weirdness no occasion).
It would be if it worked on anything except Ubuntu that is. Maybe a month ago when I tried it was different, but there was no amount of installing and tweaking I could do to get it to work on Arch.
