And so we get into the age old Mac v PC debate

You started it

I can genuinely say, hand on my heart that both of my Mac's stand head & shoulders above any PC I've ever used.
That's your experience, and a good one, but it's not definitive proof that Macs are any better than a PC, which could be made by anyone from Time to...erm...Apple.
I've been using Macs for nearly 20 years, on and off. The Classic was great if you like peering into a tiny B/W screen, then I used a few Quadras. Performas came along and they weren't so great. I then had a Powermac that was OK but hopelessly unpowerful compared to a similarly priced PC. Build quality can be anything from superb to ropey, depending on the model or country it's built in.
If you buy a PC from a decent company that uses high quality components then you're going to be just as well off than if you'd bought a well specced Mac.
I do miss the glowing Apple logo on my Macbook Pro though, feckless tart that I am.
