I have hopes that the short life on the SD cards wasn't just due to heavy use, but was due to the card being a removable part, and often in a pocket, thus subject to grit incursions. (Not that I *did* remove them often, but they were more exposed than a builtin piece of memory would be.) Do you have any knowledge of whether I am at all correct about that?

Current display resolution is sufficient for me. More would be a plus, naturally, but I'm still struggling to meet all of my important requirements.
