Wifi on Trains and Subways

Im almost 100% positive that there is no wifi on trains, and subways, which brings me to this point. People want to be able to use their tablets on their way to work.Or maybe a student has to finish something for college but needs internet access. A1 1/2 hour train ride, then you would usually read, play on your phone, sleep, relax. But what if there was internet access! Then you could get more accomplished, Send E-mails ( although you could do that on phones that have internet access) Its eaiser to send a business email on a larger sceen, like on an i-Pad, or laptop, or any other tablet. Wouldent it be nice to have that! And on planes no what, no extra fee? How would you feel about getting wifi on trains, subways, and trains? Sounds good to me!
