No, i'ts not a nasty comment, but you've interpreted it that way since you've made the same folly. I get that, that's human nature.

Yes, a RaspberryPI is a "Computer" or "Universal Machine". So literally every ACTUAL SMARTPHONE (regardless of price or ability) is a "Better Solution" than this.

a RaspberryPI for this purpose is such a waste!

"But Think Of The Children!" you cry!?

So now we're teaching the kids that the way to build a house is to buy a skyscraper and burn down the top floors? Seems like this has been goin on since the "S.T.E.M." fad and its pretty easy to see the effects if you stand back far enough.

you can run a RaspberryPI off a 9v battery too, just not for very long.
