GPRS was a godsend as it brought the always-connected, pay-for-data usage that we all know nowadays. The precursor, HSCSD, was ridiculously expensive because you paid by the minute. If my memory is correct, there was also dial-up on mobile/GSM (well, I used something before I had a phone that supported HSCSD), which was interesting, but quite useless at the time. Also, #3 makes little sense seeing as there were already cars with built-in satnav, and you had to look down, which is worse than a phone on the windshield.
