Re: 1 USB port? Seriously?
As I type I'm moving a load of data off an SD card onto my computer. The data come on an SD card, thats how we arranged to get the data off the standalone system which doesn't have an internet connection as its not connected to the internet.
Oddly enough, quite a few people still use old simple technology to move data around as not everything is connected up. We have dozens of standalone data loggers running of batterys collecting 'stuff''. No internet connection, indeed very little power, they are very low powered.
Just because you don;t need it, don;t think other people don't.
