If you get a Mac you probably won't need a large network of PC geeks. I've been using them for more than 20 years, and I'm not into DTP, graphic design or whatever - I see a computer as a tool, and the less it 'gets in the way' the better. I don't want to play the latest graphics-intensive games; I just want to write stuff, do my accounts, prepare the odd presentation, listen to stuff, play with photographs, play with music files, browse the internet, send emails and play the odd game of mah-jong. The Mac I use does all that and more perfectly well.
OK, it's 10 years old, but it really does do all I could ask of it. In that time my other half has worked her way through four PCs and complains that her current Dell is sluggish and full of bugs. In that time, her total outlay on computing stuff is probably three times mine, and I couldn't even begin to put a price on the frustration and tantrums that the PC has induced. If I bought my Mac again today (and I would if I didn't have the readies for a spanking new one), I'd probably pay about £100 for it on eBay. For me it would be worth every penny.
I've used PCs at work, and even now have a PC laptop bought 'on the company' because there are a couple of mapping applications which won't port to my Mac (new Macs can boot into Windows and run Windows stuff, but my old chugger doesn't have an Intel chip), but my computer of choice has always been a Mac.
If, however, you see using and fiddling with a computer as a hobby in and of itself, a Mac may well be rather boring for you. In which case, get a PC.
