Hey, let me know if you do. I am not a toddler (of course), but for my kayak trips I need something decent, cheap and waterproof.

Check out aLOKSAK bags. I've successfully tested my Nexus 7 tablet under the shower with one of these bags. For scientific purposes, of course.

For science, I'd put silica gel crystals in it and take it to the shower before I dunk my tablet :)

You could just use a square of cardboard... why use electronics at all :)

Because it won't tell you if there's humidity inside the bag that could potentially harm your device. Silica gel isn't electronics. It'll change color when it detects moisture.

I don't mean to sound as a luddite, this is an honest question: why would you need a raspberry pi tablet in a kayak trip?

Maybe he needs a cheap display for reviewing photos taken on the trip? Something, he might do some basic editing on? Something durable, not too expensive, that fits his needs.

Just throwing thoughts on a wall, waiting to see, that sticks.

sdoering got most of it right. I also would add backups, it doesn't feel safe keeping all your pictures on cameras sd cards for weeks. Actually, for me it's mostly backups, that's why a dirty cheap rougged tablet would be nice (cheap because I don't do many of these trips).

About $350 [1]

That's a lot. I was looking at $50-$75 price point. Don't care about screen resolution. It can be resistive touch. One can skip on storage too. But it needs to light up when you touch & make sounds. Most of all, handle all the abuse :)

You were hoping a single hand-crafted unit to be cheaper than majority of massproduced chinese crap?
