Definitely, VR dev can cost a pretty penny. The only reason I have a VR capable rig is cause I was given the CPU & GPU by a friend who reviews hardware after he was done with them.

Android has low development requirements, but you can definitely get by without a flagship phone from each of the major vendors, one mid-range device will usually suffice.

Wrt web development, why bother with a Windows VM? It either renders in Firefox & Chrome or it doesn't, and if IE/Safari can't hack it, tough luck, you get the JS free version of my web app for being a steaming pile. I'm not willing to waste resources on dying platforms, that is silly.
