Re: You do know....
Indeed. I don't want to replace my phone. And I don't know offhand whether any Android phones have built-in NTN support, and I probably wouldn't want the models that do, and I don't spend the sort of money required for the latest models on something as fragile as a phone anyway.
The Bluetooth dongle is interesting; $60/year isn't bad for a bit of insurance when hiking and camping, or just for the long drives I have to do through rural (and partly mountainous) areas where there isn't always conventional service. While I see the advantages of a rugged phone, in practice I find keeping mine in a Ziplock bag has sufficed for water-proofing thus far. (The touch screen works fine through the bag, and it doesn't even interfere significantly with taking photos, unless I really care about the image quality.)
