Why does the VMware Fusion provider cost $30 more than VMware Fusion itself? I'm not against commercial software, but the price is off-putting, particularly for personal use.
The reason is that VMware Fusion is woefully underpriced on Mac OS X systems, due to steep competition from Parallels. The equivalent on Windows is $249.
My argument is that the value you get out of something like Vagrant + VMware Fusion pays for itself in less than an hour per seat (assuming you're billing more than $79/hour). I find that to be pretty good value, rather than comparing it directly to VMware Fusion.
