I'm not taking trips like that at the moment, but I've done that sort of thing many times in the past and I intend to do it again. It put food on the table and it was more fun than anything else I could come up with.Let's face it, you're not running the Darien Gap with your 276. I've had the tablet on washboard and bouncing down roads, no problem. I don't take it i the rain, I'd rather just sit inside the truck where its dry.
I carry the DeLorme Atlas / Gazeteers as a back up. We did a two week trip through Colorado back roads with just the tablet. I'd say that was a planned unsupported outing. I've also run Michigan's UP with just a GPS and then again with a tablet. Same with Kentucky backroads. Hands down the tablet wins every time. Like I said, I'd take a satellite/road hybrid map any day of the week. Or I can switch on topo.
If I were running for months on end in a remote place I'd buy an otterbox. If the tablet craps out I can pull the SD card and use it in any other device.
I'm glad you like your 276 though.
Not everyone has the same hobbies. Some people function better in a mobile, dynamic environment like that. I may think the idea of making little models of Civil War battles is insanity, but you won't catch me suggesting it doesn't happen just because I don't think it makes sense.
Garmin did this for a reason. They aren't just throwing reinvented heritage into a vacuum. You don't have to understand or even appreciate my position when a manufacturer of such pedigree pulls something like the 276CX out of their ass.
It's targeted right at the user you just suggested doesn't exist...
I mean, it's like saying Hustler, Snapper, and Kubota should all disappear because nobody mows twenty lawns in a day. Really?
