I really want to see Google PowerMeter adopted in Sweden, I guess it will be a long time coming, but an overview of power usage would be excellent.

For that matter I would like to see Mint.com adopted by Swedish banks though I am sure they will argue that they have to do it themselves with some stupid software developed by a kid out of University that knows nothing about UI, and banks that complicate everything as much as possible.
