I would use my 3G connection to all basic surfing and especially to be able to use viber/skype anytime anywhere. To seek WiFi spots always when in urgent need for communication is just not for me. I will be most liking to use small mobile 3G router, so I can connect with my phone or laptop.
Did you see the RAC report on how much money the camera at the southern end of the M11 makes, yet has allegedy doubled collisions from people jamming on their brakes to try and avoid having their picture taken? It's all about the money in the UK, it's all about the money in Thailand.
