This is very true, Dennis. I really didn't mean to sound like one of those "nothing can kill my Mac but kryptonite" people. My bad.
I use both (an imac G5 - a powerpc version, not the new intel one) and several Windows based laptops and desktops.
My advice is that if you don't play games, and you're not a hardware junkie who likes to build computers, then get a mac. They are in my view, simpler and more intuitive. They are also, less prone to obscure and unpredictable little niggles.
However, macs DO crash and hang. A lot. IMHO about the same as Windows PCs.
My experience is that mac software also works better pc software. I like to stream video from my camcorder, edit it and put on DVDs for friends & family. Having used both macs and PCs for this purpose, all I can say is that I will NEVER, use a PC again. Having paid about £60 for Movie editing and DVD burning software, it was simply unbelievable how difficult it was to get the damn thing to work without some obscure error messages, reading unhelpful manuals and eventually finding from some online forum that the error is caused by a hardware conflict (for which you need to download the latest drivers), a Windows Registry setting or some problem with Norton Firewall (don't get me started on Norton products), or whatever.
However, after trying it on the mac, it's simply just a case of plugging in the Firewire port, using the (built in) iMovie to download the video, arrange the clips, snip them, add a few snazzy titles and effects. Open up iDVD and burn it. For a simple arrangement the whole process can take 20 minutes.
So my experience is that Macs are just generally more productive because you end up worrying less about the technology and just focus on the task.
Having said that, there remain two major gripes: first, the most catastrophic system error I have ever had was on a mac, in which I ended up losing data. When my PCs play up I can always fix them myself but in this case, the mac ended up having to go back for repair and I ended up losing all my data. I've never lost more than the odd bit of data on a PC. There's no knowing whether this is a systemic problem with the mac but my confidence in the entire platform was shaken by that experience. Of course, whatever you use, you should always back data up.
The second gripe is the lack of a right mouse button. I really can't understand how mac users can do without it.
