Well, they are "embedded systems" in that they are computers embedded in a mechanical system, but:
As such, throwing hardware at the problem to make the programming easier seems like an entirely rational approach.
All jokes aside, there are plenty of tasks out there for which the Surface Pro 3 or other full-size tablets are oo big. We have built a web app for in-class marking in tertiary software engineering lab classes, and a 7 or 8 inch tablet is the perfect device for carrying around with you and entering marks. A 5 inch phone is too fiddly to press on radiobuttons and can't fit readable descriptions for more than a couple of marking criteria on the page; a full-size tablet requires you to put it down on a desk to use and gets heavy to carry round - and the Pro 3, I suspect, would be particularly bad.
I might get a Pro 3 or its successor one day, but it will be an adjunct rather than a replacement for my own Nexus 7.
The evidence from the natural experiment that the United States has conducted vis-a-vis the rest of the developed world is stark: having large numbers of firearms, particularly handguns, in civilian hands results in far higher murder rates than would otherwise be the case. And yes, we have murders here in Australia where I live (you have four times as many per capita than we do), but we haven't a mass shooting since 1996 when we banned semi-automatic weapons and made it harder to get pistols. So, frankly, it's you who are living in a fantasyland if you think every Tom, Dick, and Harry having a gun makes you safer.
The historical evidence is overwhelming; large numbers of handguns distributed among a civilian population leads to lots of murders; automatic pistols and/or semi-automatic rifles with large magazines lead to occasional mass shootings. Getting rid of large numbers of guns also has the effect of considerably reducing suicide levels.
If you're prepared to live large numbers of unnecessary, painful, premature deaths as a society, well, that's your choice. But no amount of "but we only support the responsible use of firearms" puffery should disguise the fact that the NRA's lobbying maintains a legislative framework that virtually ensures those premature deaths will continue.
Republicans have been the primary Congressional force running interference for the old space industry, either by throwing money at the likes of ATK to build rockets that will never fly, or actively blocking SpaceX from competing with the established players on contracts.
While the big government contracting model can get crews into space, it does so at such an exorbitant price it's simply not worth it. SpaceX, or more precisely the discarding of legacy design and especially legacy contracting models that SpaceX represents, at least gives us a chance of a sustainable space program because it is far, far better value for money. It's also far more in alignment with professed Republican principles, as distinct from revealed preferences from observed behaviour.
A revived crewed space program under the old model will result in bugger-all flying, lots of money wasted, and will get cancelled soon enough. Why bother?
My take: it's not the world's biggest problem, but if it's necessary to provide comparisons with earlier papers go ahead and use Lenna, go right ahead. If you just need to illustrate a technique on human skin tones, pick something else and stop needlessly pissing people off.
