I find a lot of my development time is spent working on iOS devices. This proves to be a little difficult for me… because I’m a PC. I have nothing against Macs though. They are wonderful machines if you are willing to pony up the extra cash for one.
The one major advantage Macs have had for me over PC’s (until today) is the ability to utilize the webkit debugging tools in Safari/Chrome. On a Mac you could simply plug in your device and test away. On Windows…. not so much.
