It really depends on the application. Low-power high-function computers like phones and handhelds still needs specialist knowledge to get the most out of the machine; this also includes low-power, low-cost specialist machines like media service devices or specialised service machines. Many people never work with such constraints and so, they don't require such knowledge.
This is really just an application of using the right tool for the job. I like using other people's tools whenever possible so that I can invest my effort into ensuring the computing experience is logically correct and acceptably quick.
