I'm not sure I agree with this. WLAN hotspot coverage will never approach the ubiquity of GSM/GPRS, and neither will 3G in the short term.
The market is't exactly flooded with quality 3G handsets yet, and there is no mass market for laptop/PDAs. GPRS is appearing in most new GSM handsets though, and they have a pretty large market. My money is on email to handsets/Blackberries, MMS and telematics as the applications which will drive GPRS. We'll see if the per kb charge comes down, I'm guessing it will in time.
