Developing for Windows is in fact a pleasure. MS have more love for their development community than you realise, and this is reflected in the tools and technology they provide. .Net is incredible. Really.

The actual console window annoys me, I'll grant you that, but only in terms of fixed width and columns. PowerShell, the current standard shell for modern Windows version is really powerful. Get with the times.
> Developing on windows means piece of garbage hardware, shitty laptops till maybe a few months ago, who still cant fucking get touchpads right
Ummm... blame the manufacturers? Microsoft doesn't own Asus, Acer, HP, or any of these other companies.
The topic is whether or not to support a particular major browser, not whether you prefer Windows as a development environment or working with budget hardware. I would suggest you step back from your frothing-at-the-mouth hatred of Microsoft and determine how up-to-date, relevant and accurate your information actually is.
Do you actually use PowerShell as an interactive console on a daily basis? When I tried to learn it, it seemed powerful for scripting, but nearly impossible to use interactively. I ended up using bash under cygwin, because it seemed to be the best option available.
The same applies for Apple, you just have to download their SDK and use their Simulator - though that requires Apple hardware.
