I use my iPad for field review and I'm looking at that function primarily.
By direct transfer I mean using a card reader or a card reader plugged into a USB port.
As far as I can tell, none of the Android devices have this setup but, if I'm wrong I'd love to hear it. I've talked to various sales persons who have uniformly either had no idea or have told me it can't be done.
I've looked at Android versions from Samsung, Asus and several others.
I'm thinking that a Windows tablet which has a full USB port might be an answer with an SD card reader.
Any other thoughts?
