Would be interesting to see if any of these low-level skill folks are actually high (or higher) on mobile skills.

"Mobile skills" are likely still lower skill. Tablets and phones are mostly content consumption devices instead of content creation (photos/videos excluded). Does anyone do serious software development on a phone? How often are mobile users writing papers or prose using only their touchscreen? How many people are doing complicated video edit on an iPhone? Can those tasks be done on a table/phone? Sure, but I don't think its common.

The reason this is a problem is that it means there is a barrier between deeper computer skills and the devices/environment that people are using daily. The reason many of us became computer savvy on a desktop wasn't because we wanted to, its because we had to to get the game running we wanted or we had to write the paper we were required to. So being familiar with other uses on a computer, it is only a very mild extension to writing a script if the need arises. The only "new" or "foreign" part is the script, not the environment or interaction of where you're creating it.

With a tablet/phone as your primary device it means learning not just scripting, but learning all the skills necessary to use a computer. Its a high barrier.
