Thanks for that info. It sounds very good. What I meant by the Bluetooth question - I should probably have said download, not upload. I want to be able to extract igc files from an approved logger, which will be connected to a GliderGuider PNA. Would I be able to use Bluetooth to transfer files into the Nexus from the PNA?

I don't know, to be honest... It could work but I won't promise anything

Why don't you just connect the logger to the Nexus 7?
