I haven't been following this thread in detail, but I think there might be some misunderstanding or miscommunication. In my experience the G levels to which components are exposed (or could potentially be exposed) are quite different. They go something like this:
Airframe-mounted components - 4 G's or so (more for hard-core aerobatics)
Unsprung weight (landing gear below the springs) - as high as 40 G's, but more like 20 G's
Engine-mounted components - 20 G's, but as high as 40 G's at the cylinder
heads
I don't know how anything could be exposed to 70 G's of externally-driven G forces. Maybe internal to some components G levels are that high - certainly inside the engine or at the propeller tips, but otherwise, I don't think so. You can keep your laptop :-).

70 G’s? That’s an awful lot of force. Wouldn’t your pump be experiencing that as well? I think my pump at least 10 lbs. Isn’t that like 700lbs? That’s pretty scary, maybe I should beef up my mount a bit.
If there is that much vibration in a typical airplane, I wonder if I should leave my laptop at home. I’m not sure I want it experiencing those kinds of vibrations. That would really mess up my HD.
