I've been using the stock SD card for 4 months ...
I had every intention of replacing the stock card as soon as my console arrived but somehow just ... Never got to it? I got my R36S in February and I've been using and abusing the console daily. Putting games, movies, music, an ereader onto it, personalizing everything I possibly can ... My console doesn't have wifi so I have to copy directly onto the card from my computer.
Apparently I'm one of those people who love tinkering/finding out what can be done with it more than actually playing, although I've put quite a lot of hours into Spyro as well. I've also printed a case for the console, I'm thinking of printing a grip, of painting the housing, buying some thumbstick grips...
Anyway, I've probably taken the card out of the console more than 200 times since I've had it but I still haven't had a single problem (other than 32gb not being enough haha). Has anyone had the stock card actually poop out on them or has everyone just been scared out of not replacing? Just curious.
I do keep a computer copy of everything that is on my console just in case.
