I've just been looking at the UK pricing of Windows 7 on pre-order. As usual the prices are higher here than in the US (even taking into account exchange rate, tax etc).

According to Microsoft's online store (and prices are cheaper with other online retailers):

Follow up:

Home Premium is £79.99
Professional is £189.99
Ultimate is £199.99

Now is it just me or does it seem that if you are spending £189.99 on the Professional edition, then the Ultimate has to be worth it for the extra £10?
