It's sad to see otherwise talented developers focusing on the process more than the product, and putting their craft above the user experience. After all, it's all about the users. Doing good work and making excuses don't mix.

If you use any excuse not to test on any browsers in any Windows environments, you're ignoring the fact that the vast majority of users are on the Windows platform -- ~90% worldwide, ~81% in the US. I'm talking OS, not browser. (If you think there's not much difference, try borrowing a Windows machine and viewing the way most @font-face rendering works on that platform.)

And if you prescribe to the thought "my users are mostly on Mac," your growth will be severely limited if you're ignoring 80-90% of the users out there.

Development & testing are two separate tasks. Don't confuse their respective toolsets.
