I love Simple (@simplify) and I want it here in the UK right NOW!
Simple (or BankSimple, as it was previously) has been tempting me with their beautiful interfaces and intelligent marketing since this time last year. The iPhone app (above) looks absolutely lick-able. The whole idea and approach has been an ongoing source of inspiration to me and my work on morethan.com. I'm pretty much ready to sign up right now and I've never used the service.
