Is it time to swap your Mac for a Windows laptop?

I've been an Apple user for over a decade, ever since I picked up a refurbished 17in PowerBook back in 2005 to replace my ailing Windows XP box. But last month, after Apple announced its most expensive new MacBook Pros in almost 15 years, I reconsidered my decision for the first time and, for the past few weeks, I've been back on a Windows PC. My first three computers were PCs, although the house I grew up in had an ailing, hated Power Mac Performa. My reasons for switching in my teens were fairly simple: I'd been playing fewer and fewer PC games, and spending increasing amounts of time using my computer to manage the music library linked to my iPod. I was one of those switchers, surprised by the elegance of Apple's music player and convinced to take the plunge into their full desktop operating system.
