When intially setting up my sony e reader, the only options for location were US and Canada.I just chose US, will this be ok?Just looke don the sony store as well and every book to buy is in USD

Thanks

Did you buy it in the UK? I'd be concerned about losing out through currency exchange rates if purchasing in USD.

I guess the User Manual does not help - what about the Sony website? Is there a support forum for their e-readers which you could use for help?
