Well, if you have a PC that is knackered, through old age or maybe just the fact that it's been destroyed by pesky spyware and viruses, or maybe you just hate it, then it makes sense to be able to buy a headless Mac without the expense of the peripherals. For people who want to change but don't want to spend the money on new monitors and the like, the MiniMac is a great option. To answer your questions 1) if you have wifi or firewire or some cable connection then it's relatively easy. You can connect to the PC from your Mac and just copy stuff across. If you haven't, then you'd have trouble copying onto a new PC anyway and would have to take the HD and add it in as a second drive. (That's what I've always done in the past). When I changed, though, I discovered that I actually didn't need half the stuff on my PC and have never moved it over. My PC has become almost redundant these days, and as soon as I get a really good Mac (rather than this lovely, but ancient, TiBook), I will transfer everything over and my PC will become a back-up/storage device. Regarding 2) well, that realy does depend. Some people hate Macs, but personally I think that Mac OS X is a far, far better OS than any of the flavours of Windows and when the new version, Tiger, comes out later this year it will be even spiffier. It just makes every day working that bit more enjoyable. The apps are generally more stable, and less prone to inexplicable death, day to day menial tasks are easier, and it deals with multimedia much better than a PC. (Codec bloat in video means I can hardly ever get downloaded videos to work on my PC, but they almost always work on my Mac.) The thing is, there *is* a learning curve for people changing over, but I personally think it is worth it. But then, I have been drooling over Macs for the last 13 years and have only just got one of my own, so I freely admit to bias.
