Well, as I was stuck in traffic for 45 minutes today, on a motorway, with the nearest starbucks 40 miles away, I was glad for the 3G model that allowed me to look at the traffic news, do a bit of e-mail, remotely set my PVR to record the World Cup match I was likely to miss the start of... Do a bit of browsing.. I could have even ordered a pizza but thankfully the road started to move..
If only they had wifi on the motorway
