(I heard there are desktop systems running Android, complete with mouse and keyboard - that would be a very different story, of course!)
One of those $100 Intel-powered Android tablets with the Z3745 processors has a processor that, core for core, equals a Pentium III or better. But instead of one core, it has four of them. And dramatically higher memory bandwidth. And SIMD. And a GPU. And shockingly fast flash storage.
And it's probably running at least a 1280x720 screen, though some options obviously go dramatically higher.
In ~2000, when these sorts of specs were common, we did all of our office work, software development, etc, on much less power.
Also, I like having a physical keyboard. With a tablet, I end up using one hand to hold the tablet and one hand for typing. :-|
Like I said, on different devices the situation might be quite different, but my tablet is no good for working.
