That old question crops up now and again. It's a bit like
- vegetarian or carnivore?
- are women better than men? (I really don't want to open up that can of worms)
- how old's Mae West? (classic line from Hitchcock's 'The 39 Steps')
It's right that Macs cost more, but then quality comes at a price.
I've owned Macs for 8 years and have had 2 viruses in that whole lifetime, both in Microsoft documents. I used a 2.5Ghz Dell at work and it ran SLOWER than my old 533Mhz Mac at home. I've seen inside another PC whilst the IT bloke opened it up at work and it looked a complete mess. My friend had a brand new PC for under half a year and the motherboard sizzled out.
It obviously sounds like I'm PC bashing, but I can only go by my own experience. I'm sure a good PC is great, but an over-priced Mac is superb.
