Has any experience using nexus7 with Skydemon as it looks like an ideal size and aide in our Jab 430 and priced buy .

I am running SD on a Nexus 7. I like it for planning. However, I am not using it in cockpit, and my impression is that the brightness (or lack of it) would be a problem. I am running SD on a GliderGuider for in cockpit use - the smaller (5 inch) size suits me better, and the brightness is superb. However, this is a Win CE unit, which does not have the full planning facilities, so you have to do your planning on a PC and then sync the mobile unit. I don't have a way of syncing the Win CE unit from the Nexus 7 - I think it needs to be synced with a USB connection.
