With the release of Windows Vista, Microsoft is selling upgrades at £100 to £250, with the American prices at $100 to $249. With the current exchange rates that means we're paying double what the Americans do. With 'normal' rates of $1.6 to the £1 then we'd be charged ~£60-£150.
The best bit is Bill Gate's quote as to why we're paying the dollar price in pounds and getting ripped off:
We try to keep our prices largely in line from country to country... but with price you do generally get some things that get a bit out of alignment as currencies go up and down.
So, following that logic, when was the last time that the dollar was exactly equal to the pound? To the best of my knowledge, never!
Thank goodness I'm not planning on 'upgrading' to Vista any time soon (if at all)!
