Already made the jump
I made the jump to Apple about 5 years ago and have never regretted it. Yes the kit is expensive, but like the tools we use in the workshop, you definitely get what you pay for.
I have no choice but to use MS windows machines at work on a daily basis, and I have to say the operating system is as crap today as it was five years ago, if not worse. I hate it with a vengeance and
My Apple Macbook Pro only gets turned off or rebooted once in a blue moon, the occasional updates for the software are usually automatically installed in the background, and annual OSX version updates from Apple are free, unlike the hugely inflated prices from MS for new versions of 'windoze'. It turns on almost immediately, and the machine is a pleasure to use. Yes of course, when switching from MS to Apple, there will always be a few problems until you understand how the apple system works, but I for one will never buy a MS based machine again!
