I've left mine on 24/7 and had no problems for about 3 weeks. Then the battery died - guessing the charger wasn't seated right. I got it recharged in house overnight, back in car, and again has been good, but now I turn it off when I stop the car (at least at night - it does seem to run a long time without much problem).
Performance has been steady (ableit slow, 10-20kbps). Just got my home ftp site running, and it was autoloading files every minute, like a champ.
Still running down my original $10 credit, too!
