Bingo. My home office computer is a Mac, I love it. Built in BSD tools if I need to do work that uses them, great editing tools for what I do, and I LOVE the iLife suite. For plugging in my camera, grabbing family photos, sending them off to print, uploading to Facebook, etc., is all really easy. Editing videos is easy, etc.
The fact that this stuff just works is important to me.
Could I crunch some of the big spreadsheets I do in Excel on Excel for Mac... not without a lot of pain. But can I knock off a letter, edit an image, crop something from a website to send (Preview is a killer app, opens nearly instantaneously without the aggravation of Adobe reader), etc. It's easy and stays out of my way.
And the sleep actually works, I can pop into the office, do something for 10 minutes, and leave to go back to my life, without my work flow being interrupted.
I know that Windows added their version of Fast User Switching, and maybe Windows 7 got it right, but nothing seemed as seamless as on OS X.
I use a Blackberry as my business connectivity Smart Phone, and I like the keyboard, but if it wasn't a business tool, I'd be all over an iPhone. I don't need more time wasting equipment or I'd look at an iPad, just doesn't fit my life, but I appreciate what it does.
Office work, yeah, the Mac is second fiddle, but Quickbooks online is "enough" for me, don't want to switch back to Quickbooks, mostly because I can check into thinks from home or the office, which is pretty nice without hauling a laptop around.
Apple makes cool products for people that benefit from them. That isn't everybody, but they have a decent sized customer base because upper income professionals with families and limited free time happens to be a lucrative market. Good for them, they build a better mousetrap.
