That's exactly My point! If you're developing on Windows for Windows then you're golden but most of us have to deploy to a Linux server environment most of the time unless you're a pure Windows developers.

You may run into some issues when you switch to Mac but luckily there are far more resources out there to help you out that work on both Mac and Linux than there are for Windows. Windows isn't bad, it's just different and that different-ness can be a pain for the average developer.
