Microsoft would really do well supporting a truly great UNIX layer.
I wouldn't say stupidly. Open source projects just don't prioritize Windows development.
Total cost (including the Intel SSD) was £726 or $1049 at today's rate (exc. VAT). So didn't cost a bomb and gives me a lightening fast machine, windows for desktop duties, debian for dev, a 1920x1080 display, easily replaceable battery/ram/disk and no issue driving multiple monitors.
It's also stupid to assume that your application will work seamlessly between Windows and Unix-like systems just by making sure that the path separators are OS-agnostic.
And once you know how the C++ compilation works with VC++, the problems are minimized. ( i mostly come this accross with Python)
It isn't a hassle free road though
Edit:. The Pi is just for experimenting, no GUI required ;)
Payed 550€ for my laptop ( 8 gb, ..) 2 years ago, everything is still working fine and it's still enough ( Visual Studio is supposed to be a "heavy" program). = 23 € / month till now and still dropping... And it's hardly game over with my laptop. When i'm at 3 years, it will cost me about 15,2 € / month.
I'll probably use it for longer. But let's say i don't have any costs and sell the laptop for 150 €, that makes it 11,2 € / month.
PS. No repairs required untill date
Edit: You can install Linux on it too or dualboot it ( i did this a long time, but didn't feel the need for it now)
