Because VMware has essentially abandoned their client virtualization software? (Workstation 11 is a paid minor bug fix.) While it's way better than VirtualBox, it's still annoying. Stuff like USB devices will randomly not work. You need more system resources, which heats up the machine, making it hot to the touch. Oh and it crashes at times, too. With Windows-on-Windows setup, I was having daily crashes. VMware doesn't seem to care and offers no support with the product (gotta buy a company support plan). They even had a kb article to the effect of "Known issue: Workstation crashes when you run Office 2007". It's usable, just a bit annoying. I feel little option but to run Windows as a host OS in order to get best driver/video/battery support, so VMware is essentially mandatory. It's also a huge attack surface.
