I would not recommend this. Lots of vibration, and plenty of hard hits even on our squishy bikes. Plus the Cell chips in tables are even less superior to their cell phone counterparts. They are often 3g, older chips. I would not expect a good quality cell signal in the mountains out of a tablet.
I can't comment for certain, but I think a tablet laying flat on my tank bag, is pretty robust construction...we did use it briefly in our truck, for guidance/mapping when it had an active SIMM chip, but when the screen got a crack in it, we retired it to be used at home, wi-fi only.. and when I mentioned it, I also mentioned using a remotely mounted
GPS antenna to pull signal.. (
not using a simm card, or phone services for location), but plugged into the tablet to be used as a simple "screen".. I also have a small Laptop computer, ACER model, with a 9" screen, it has a solid state hard drive,multiple USB ports, a 12v lighter plug for aux power, and has been carried for thousands of miles in my side bags without failure.. it's really compact, and I've considered using it strapped to my tank bag also in combo with a GPS antenna, and programs.. Garmin and a few others make them, and they are very low $$
