I would say YES it's important!

I have a 10.1" Android tablet with no cell-phone capability, but it has 802.11 B/G/N.  I'm running a hacked-up WRT54GS w/OpenWRT, AX.25 stack, and two DE-9 serial ports.  I could put something like that in the Jeep, hook a KISS TNC to it, and use the tablet as an APRS messaging/mapping display over 802.11 (thanks for the idea Bill).  I'd have to hack up my 2nd WRT54GS to do this 'cuz I want to keep that first router in the shack.

OpenStreetMaps in Shapefile format should work nicely.  We use that format in Xastir for offline maps, and it gives you the capability to create or use many other maps that are available in Shapefile format.  Libraries are freely available for this format and the map spec is published.

I saw a picture somebody posted with a tablet mounted in their dash.  Looked very nice.
