One option is to run compute-heavy stuff on a networked server, which you SSH into from a lightweight phone/tablet/Chromebook. I can definitely see myself working like that, if I could get a phone or tablet with a docking station.
SSH isn't as light as many people think, just because your CISC desktop yawns at it doesn't mean it's not computationally heavy.
Wow, I installed Windows 8 on a T7100 (1.8Ghz) and it runs super smoothly, but some people were complaining of Tegra 3 windows RT tablet being slow? (try googling "tegra 3 windows RT slow") That is weird! Can we really trust those benchmark for real day to day comparison? Or maybe I don't have the same speed expectation as the tablet users?

Is it just me or is that A7 performance crazy impressive? Especially comparing an iphone to the size of an i7 + cooling + power
Yep, I think the A8 (or A7X) could be really close to the performances of entry level CPUs used in MacBook air! An A7 scores 2564 and an i3-3217U 3095. But if you look at the Atom Bay Trail, which scores 2630, you see that Intel did a nice coming back in the mobile segment, at least for tablets.
In the case of a quad cortex A7, like the one in the Moto G, or the MediaTek MT6589 in the bench comparison, we see that the performances are too bad to replace a laptop. With a score of 1258 it is comparable of the best good old netbooks with Intel Atom.
For historical perspective, Core 2 Duos are from 2006/7. And T7200 is a laptop version, slower than desktop equivalents of the same era.
Desktop CPUs are still much, much faster than phone CPUs. Here's a table with lots of numbers:

The iPhone 5s, with the "desktop class" A7 chip, has about 15% of the computing power of an i7 4770k, by this benchmark.

Trivial work, like text editing, light photo manipulation, sure. Anything that could be done on a PC 15 years ago, sure. But they're nowhere near one another.
