cygwin is not supported by node, but yeoman website recommends using it on windows

[sam-github]

A customer of ours just came to us asking why our generator doesn't work on cygwin... we wondered why they were using cygwin, and we found:

http://yeoman.io/codelab/setup.html

That's not good advice, node doesn't work well on cygwin, and the terminal support required by yo is particularly broken. See comments in this thread:

nodejs/node-v0.x-archive#5618

Please open issue on yeoman/yeoman.io - even better, send a PR suggesting PowerShell instead.

Or git bash.

or OSX or *nix

We should just add this to yo :p

var open = require('opn');

if (process.platform === 'win32') {
  open('http://www.ubuntu.com/download/desktop');
  process.exit();
}

Here comes the OS trolls!

Ok removed the line on the codelab. We'll need to rebuild in a few to update it on the live website.

Finally decided to go with cmd.exe - it sucks, but it's mostly the default on Windows. Powershell is installed by default too and way better, but the default 80' blue theme is so bad it would scare people away. (I should write an article at some point on how to set up slicker terminal on windows)
