A good long lasting large Android phone on a handle bar mount that is rigged up to a USB charging port on your bike is the most useful travel buddy. It can display a saved Google Map route and give you turn by turn directions verbally and graphically.
It is also your phone and your internet whenever you need it and actually have a tower signal.
A real modern current Android tablet (not a Fire tablet) can do everything but be your phone.
You have seen me do this sort of stuff in trips past. It is neat, but it is not not without complications.
Warning:
Fire tablets lack a GPS chip and all assorted GPS functionality.

Mike, please understand you simply haven't got some of the advanced android skills that are going to be needed to make the best use of such a Google-ish rig.
For years you have used older Garmin type stuff instead. It got you there, but it can only deal with older stored maps and center point to center point navigation & directions.
A large Android phone is always totally current, right up to road closures that just took place today.
Chromebooks uses the chrome browser, same as on your computer but they have no GPS chip. Fire tablets can be tricked to use chrome after a limited fashion, but you lack all GPS functionality on a Fire Tablet because it totally lacks a GPS chip too. Chromebooks also lack a GPS chip, so they are out of the running too.
Like I said, a large Android phone is your best bet.
