This is one of the reasons I’ve switched from Windows to Mac:
As a web developer, it’s essential to be able to test a fresh page in as many browsers and environments as possible.
You can’t do this on Windows, because there’s no way to emulate Mac OS X on Windows. But on a Mac, you can emulate anything, including Ubuntu and other flavors of Linux (not shown).
Shown above are:
FireFox, Safari, and Opera are running as native OS X apps. IE6 is running through ies4osx, and IE7 is running as a native Windows XP app using VMware Fusion in “Unity” mode. Unity mode allows you to hide the Windows desktop on a Mac so you see only the apps that are running. They then interact and operate just like separate processes on the Mac. Yes, all 5 browsers were running on my Mac OS X desktop at the time I took this screen shot. Super f’ing cool. And yes, not only does Windows run faster on a Mac (not in VM mode, rather using Boot Camp), but it looks better on a Mac.
Here’s a video that shows VMware Fusion’s Unity feature:
