Hi
Just thought I'd post to answer a couple of those questions about iTunes accounts.
I've had a iPad picked up for me by a friend in the states (so I only paid the $499!) and brought back, lucky me the last day he was over there was the saturday!
Anyway, I have a regular UK iTunes account. Very pleased with the iPad (posted some thoughts on my blog
http://www.scattershot.co.uk/tech) but couldn't access the app store on the device and couldn't donwload any of the iWorks apps or iBooks as they are not in the UK store as yet.
Purchased a iTunes gift card from this guy via facebook:

As reading around he seems to be the cheapest legit person. Once I'd been added as a friend I purchased something like $40 of credit and was emailed the codes instantly (like within 20 seconds).
Then just changed my address to an address of an apple store in new york and changed my payment details to the card. Job done I've now downloaded the apps I want and they co-exist happily with my other legit British bought content.
Don't think I've done anything wrong in this and I can now put my ePub books on there that I used to read on my Sony PRS505
My biggest critiscm now though is just how poor the app store is on the device, it has far less menus and areas than the iPhone version, which, considering the already huge proliferation of apps makes finding stuff really hard.
Still, very happy....
