Not sure on the technical details of exactly how long they last, but I've heard similar things several times before.
Always depressing to be reminded of this. Haven't had many fail, but honestly haven't tried a lot of my 3DS/Vita games in a while, so who knows.
If nothing else tho, it's nice to have an excuse to revisit some things. Once you boot it up, you might find yourself enjoying the reminiscing. :)
For not playing well without the touch screen, there's modern SBC clones like the Anbernic RG DS. Don't know how good they are but they exist.
RG DS doesn't have enough horsepower for 3DS. Some select titles work but stock Android eats up any overhead it might've had.
The Ayn Thor can do more 3DS (and Wii U).
