Only £50? The downside is that you have to live in the UK!

Here in the US, there is a greater disparity (see my comments above about the Best Buy ad) Most buyers aren't mother board/chipset/frontside cache/bus speed savy and the low price of Apple stuff isn't as apparent to them as it is to you.
I don't see the downside? Everything's cheaper in the US.
For example, the same 24" 2.4GHZ iMac on the Apple US store is $1,799 (£902) which is around $500 (£250) cheaper than the UK price
the same Dell system in the US is $1,778 (£892) $420 (£210) cheaper than the UK price and ONLY $21 CHEAPER THAN THE IMAC!!!
Saying that most buyers aren't motherboard/chipset/frontside cache/bus speed savy, is not true at all. I contribute on a number of forums (mostly PC Hardware based), and people from the US crave the exact same thing as people in the UK when looking to build computers (especially for gaming).
Also, that wasn't my point, but Apple use high quality components that use the higher quality chipsets and FSB's, so it is unfair and unreasonable to compare these with cheaper systems that use cheaper 'VALUE' components. (it is possible to build a full computer in the UK for around $600 (£300), I know, I've just built one), but I also know that the parts were far lower quality than that of my own PC which cost $2800 (£1400).
Edit: Isn't your powerbook getting on in years? Hopefully they come out with a decent MBP at MWSF because I need to replace several. (damn I hate that you can't buy them with just 1 2GB RAM chip!!!)
Yes, I agree my powerbook is getting on, but it's currently with my insurance company as my girlfriend broke the screen, so when I get it back, I will be selling it and depending on what happens at MacWorld, I'll be replacing it
