This is a very valid point. We've encountered a lot of issues around this when developing Screenly (https://www.screenlyapp.com https://www.screenlyapp.com). Firstly, do careful due diligence on the SD cards (quality between different vendors/models varies a lot). Secondly, make sure to move all directories with frequent writes (such as /var/log) to ramdisk. This will increase the life span by a lot.
