"Telephones are a pain in the ass to use so why buy one?
If someone has a telephone then fine...its easy as hell to use...But the majority of people on the planet don't have telephones. "
Seriously...your using a telephone as an ease of utilization example?
Really bad example, phones started as a giant peace with no real need for technical understanding, you had to pick up and press a button and ask the operator to connect you with the person who you want to call which happened to be a person's name instead of a number... then technology evolved while we were using phones, they add something each time... and now we end up with the smart mobiles that operates as computers....it surely didn't happen over night but it took many decades to get here.
