However, I'm not that interested in a zillion flavors of Linux.
I would be willing to pay for a box which comes with Windows and Visual Studio preinstalled (plus git, cmake, bash, etc):
In other words, an up to date development machine based on WinXP, Vista, 8, X, etc.
The main reason is that it takes hours if not an entire day to install all this stuff and run all the updates required to configure it.
As a Mac user writing cross platform C++, I sometimes need to test my app on various flavors of windows and compile the code on various flavors of compilers.
Keeping 30-50GB VM files ( for different versions of windows ) on my SSD is kind of wasteful, since I only need these boxes once every month or so..
I would easily part with $5 or $10 or even $20 (if it's very urgent) for an up-to-date box like that ..
