* Apple doesn't let the CapsLock key act as an NVDA or Jaws key. Sound editing is also too slow, and so is editing Word documents if there are comments in the doc. Since Jaws with Eloquence or Vocalizer 2 is so incredibly fluid (until it crashes), I always get immediately frustrated with Fusion for this reason and stick to Bootcamp. Exactly the same subjective performance, in fact. * Typing lag is noticeable, whether on my I7 MBA or my touchbar MBP. So, it's very much like having two computers running through the same speakers. I have a Windows keyboard plugged into my Mac and I can actually work in Windows even while my Mac is focussed away from VMWare. * THere's a sort of 'hack' that lets you connect keyboards directly to the VM without the Mac receiving input (you can google it: two lines in the vmx file is all it takes).

* The newest 8th gen processors bring quad-core to ultrabooks, and that should make Fusion a much better option going forward.

* Convenient as heck for launching the occasional program while staying connected to I-stuff like messages and Facetime. Even cut and paste between operating systems.
