I am new to the Mac. I purchased a MBP about 2 months ago. I was fed up with the twitchiness of Windows and made the switch. Clearly, THE Killer app for the Mac is the OS itself. It is more stable than a window system though it does act up from time to time but, overall, the UI for OS X is a significant leap better than windows XP or vista. So I have no regrets. But beyond that, the thing I’ve been noticing is the lack of ‘killer apps’ that are Mac-specific. The number of apps in virtually every discipline for windows is extensive and the entertainment/game options for a windows system are equally extensive. Weather they will induce the infamous BSOD is another matter… So have the Mac-specific developers abandoned the platform for the more lucrative windows market? Where are the ‘really cool’ apps that can only run on a Mac?
