Just as I am on my morning 30 minute train ride I am seeing ever more people who are using their mobile devices not only for voice calls (few) or SMS (quite some) but also for browsing the web, checking their email or using an IM program of some sort to communicate (quite many). On this particular train, the network coverage of the network I use is excellent except for in one spot where I loose the network for a minute. And already that is annoying. My experience on other train routes is not so favorable. So I can't help but wonder if in the future an even better way to differentiate from other network operators than in the past when mobile use was lower is to have good coverage along railway lines for those millions of daily commuters? I can see many commuters changing mobile networks when they see that others seem to have a much better experience. I wonder if those people making the decisions of where to expand network coverage do a daily commute on a train?
