At the moment, Gdgt seems to use data for the US as its primary source, giving prices in dollars and release dates relative to their stateside release. It would be good if there could either be a setting for users to set their location, and this would update fields across the site.
Or there could be more fields when filling out gadget information during submission which include the addition of pricing for other countries and release dates too.
The last discussion on this went nowhere, and that was 3 years ago. I think it's high time to bring it up again.
