Well, all Mac owners say that. The truth is that they usually have less problems with a Mac because they can do less on OS X than they can do on Windows. OS X has a Unix foundation, but most Mac users don't even know how to get there or what to do with the Terminal. They stay on the GUI level - and that GUI level has a rather limited features set when compared to a Linux or Windows system.
Windows and Linux give you more rope to strangle yourself with. Apple keeps its users on a short leash. That creates the illusion that Macs are more reliable than Windows systems.
And Macs -are- overpriced. You pay a premium for the brand logo and the design. Which is okay when you like their design. But let's not fool ourselves by believing that you get better hardware with a Mac; when you spend the same amount of money on a PC, you'll get MUCH more bang for the buck. And you'll even get better support from Dell than you will ever get from Apple.
Anyway, none of this is the topic here. I don't own any Apple stocks, but obviously they're doing very well. Good for them. Let's see how long this strain of fortune lasts without Steve Jobs. We know what happened with Microsoft after Bill Gates left the company and left it in the hand of somebody else.
When the Mac Pros are fresh, price out the equivalent HP or Dell workstation. I think you'll find very little difference. Yes, I know that the MacPros haven't dropped in price or been updated. There isn't an apple to apple comparison right now. But in the past, their notebooks and towers have been on par or occasionally cheaper. And the build quality and customer satisfaction says it all.
I mean, my father in law just bought a nice i5 desktop system from Vision computers with 8gb of RAM for $1500. WTF? You can get an i7 iMac with built in screen for not much more. It's pretty established that iMacs are an amazing deal. What with the best monitors in the biz built in. (I have a DELL monitor too btw - pos by comparison).
You say linux and windows give you more power features... in my experience windows users are the masses. They definitely don't dig into the power of the computer they have. eMail, web browsing, word processing like the rest of the world. It's only in geekdom circles that people are digging into terminal and unix or dos or whatever you've got there on the PC. The point being - on Mac or PC, 99.9% of the users could give a rats behind. They just want it to work. And having it work longer and hold it's resole value isn't too shabby either.
Let's just hope Apple gets back to making some awesome towers.
