I understand why some may laugh or poke fun but I honestly think it is a valid question and it will be around for a while. Face it, our phones and other touchscreen devices are constantly evolving and becoming more useful in the field. Maybe you aren't using it to send a text message but how many use their phone as their GPS or camera or E-book or digiscoping camera or music player or note pad or weather station. There are tons of valid reasons to use a touchscreen device in the field and when it is cold, I probably wouldn't want to have to take my gloves off all the time either.
