Yeah, I've had quite a few people -- more often than not my wife's work colleagues -- come over to the house and say something along the lines of, 'Wow, it's really cool looking, but how can you use a mouse with only one button?" (This was before I shelled out for a Mighty Mouse.) They have one "sunflower" iMac at work -- yes, one for the entire company -- that's not properly maintained and it's the butt of many office jokes. One girl said snottily, "It's crazy... you have to drag a disk to the trash to eject it." And quite a few of them get angry that they have to open so many files on the Mac because the PCs can't read them. To me, that's proof of the Mac's superiority; but to them, it's an inconvenience.
The copy team recently switched to Macs at the agency where I'm freelancing. A lot of folks grumble about the speed of the computers in general and apps like Powerpoint in particular. But these are six- or seven-year-old 400Mhz PowerMac G4s, and they replaced one-year-old Dells. So I can put it in perspective, whereas they just see Macs as being slow.
But then there's the other extreme. My wife's sister came to visit us and spent practically the whole weekend playing on my iMac G5 (PhotoBooth, iPhoto, and so on). My wife's brother and his girlfriend thought that our iBook G3 was new until she told them it was bought five years ago. The boyfriend of one of my wife's friends spent about ten minutes circling around my iMac and marveling at its form factor: "Can you believe it?" he kept saying. "That's the whole computer right there." My own sister, who I helped switch to an Intel iMac, has turned into a huge fan, and continually raves about it to my mother.
As for me, I'm continually amazed by how well our older iBook stands up in day-to-day use. I couldn't help but compare it to a Tiny (a UK computer company) laptop, which we ditched about a year ago when I got the iMac and passed the iBook over to my wife. Both laptops were purchased at the same time and the iBook was slightly more expensive, I think, but that damn Tiny was absolutely flipping useless by its second year. No wireless, no ethernet port, flaky CD-ROM drive (no burner), struggling to run Windows 98 at an acceptable speed, and always littered with spyware after a short Internet session on dial-up. Her Dad, who'd bought it for her, thought I was being a pompous Mac zealot when we handed it back to him, saying it was no longer much use to us. Despite having never used a Mac for longer than ten minutes, he's one of these classic types who cites all the Mac myths -- no software, too expensive, good only for graphics work, Windows' popularity is a sign of its superiority, Apple's going to go out of business, and so on -- when you try to have an informed, level-headed discussion about it.
