The people who do not need a smartphone, a tablet, or a HUD shouldn't purchase one. If they feel pressure from society to buy one or just want to see what all the fuss is about, then that's their choice.

People who purchase one for the games are doing nothing but providing funding to help improve the technology for the people who actually do have uses for smart-phones.

There are TONS of practical uses for smart-phones, but there are also billions of people living on this planet who don't have a use for them.

And that's OK. Not everyone needs a smartphone, but that wasn't my point. My point was that many people (even tech people) immediately ask this question in a dismissive way before they have even started to think about what this technology can be used for.

I know people who thought smartphones weren't for them, but suddenly they discovered they were easier to use than their old Nokia phone and had QWERTY keyboards so they could write text messages without learning T9. I never imagined that a tablet would be so useful for flying and didn't see a need for one before that.

I don't need a smartphone, but it's convenient and useful.
