One nuance of the first few iterations of any new design is that rarely comes optimized in every important aspect from scratch.
It is very difficult to cover everything, when we are creating something new from the ground up. The creation process is by itself a very good sink of our cognitive energy and focus, leaving little room for a more pedantic mode of thought.
It is fairly interesting that just as with other "things" that I have equipped my house with, this Kiosk and other IoT gadgetry proved to be of relevance not just for my geek person, but for my family as well. For example my wife likes to keep track of the vacuum cleaner progress. Having its map and progress show up automatically when it starts cleaning, proved to be quite useful in this sense:
For some time I have been using the same Raspberry Pi 2 v1.1 as the infrastructure for my Hass.io instance. It proved to perform quite reliably over the approximately 18 months I have been using it 24x7. From that time during approximately 1 year I used the same SanDisk Ultra XC I 64 GB MicroSD card:
Just for precaution I have later switched to a similar card, a SanDisk Ultra HC I 32 GB, and moved my Hass.io installation onto it:
