Thanks for the analogy! I used to analogize a computer to an office. I did this since students often have a tough time conceptualizing the role of memory (especially with that misleading name), so my analogy compared memory to the desk space. However, I would always worry students would make some connection between the analogy "desk top" with the computer term "desktop" and get confused.
The kitchen analogy uses "counter top", so it avoids this potential confusion, plus kitchens are probably more relatable and interesting to the students.
