Not sure how many people will care, but Hotmail UK is now available - you can get your own hotmail.co.uk email address!
I've registered for one just for the sake of it, and it is only 25MB instead of the 250MB that they are upgrading .coms to, but it is still more than the original .coms.
I've yet to work out whether to move over to using .co.uk - its what I'd do if I ever got a .com and a .co.uk for here or dotPrograms (use the .uk and point the .com at it!)
