It's more that people have a higher expectation of what a device can to, and that generally means what the software can do.

I mean right now there are computers you can get that are orders of magnitude better in every dimension than the first Apple computer, that you can buy for less than $100 (I'm talking about the Pi and its ilk). But to make it do something useful there has to be a lot more effort expended to add peripherals and write proper software to match people's expectations.
