So my recent work with CompeGPS and TwoNav (see
http://www.laptopgpsworld.com/5528-compegps-land-mac-windows) have me thinking about a tablet to use in the car. I think a ~8" screen will be a good size, am currently using a Garmin Dezl 760 with a 7" screen and homebrew mount. Here it is with one of my own maps as well as my hack to the user interface. Would probably mount the tablet in the same spot.
Initially I thought about the iPad Mini (original 16gb version is $250 new or $200 certified Apple refurb). But I'm reading the screen doesn't do well in bright light. I have learned the hard way that screen brightness is really important, and that's one thing that Garmin does well. I struggled with my HP Slate 500 (Windows 7 tablet) and MobilePC for awhile, but that screen was terrible - not very bright and awful touch response.
Have been reading a lot about the Samsung Galaxy Tab S 8.4" Super AMOLED screen. Is this the best screen for bright light? Current price is $300 for the 16gb model at Best Buy.
I have Macs, Windows machines and an iPhone, never owned an Android device before. But it seems like a good match for use in the car. I believe it already has an internal GPS as opposed to the iPad Mini where only the cellular version has the GPS. I have the Garmin GLO, so that's not a big deal however.
If I use the TwoNav app, the platform doesn't matter, it's available on both iOS and Android. But there are a couple other Android apps that might be of interest, like OruxMaps and BackCountry Navigator that are only available on Android. And the ability to add a memory card is also a plus for Android. My main usage will be with maps that I make myself, primarily as a "moving map". I don't care much about other apps, movies, games, mail, web browsers, etc, this would really just be for maps/navigation.
Garmin StreetPilot is only available on iOS, I have the Western Europe version on my iPhone and used it for a trip last year. It is quite similar to the Nuvi, but very limited in that you can't add your own maps and can't even import waypoints. So I don't really think I'll miss it.
Any recommendations for other tablets with bright screens?
