Tried it once- fell behind about 5 years. In my opinion, the people that devise these ideas are living in a dream world where people have all of this free time to accomplish these checklists. I am happy when I find time to clean my furnace filter every month. When I had a standard water heater I rarely remembered to drain the tank of sediment. Like the majority of people, when it breaks I fix it.
In truth, the only religious maintenance I do is on the furnace. I know that when it goes bad is when I really need it (never heard of a furnace breaking in the summer). Clean it out thoroughly in the spring and it will be ready for the fall.
This is all my opinion and maybe there are some people who actually do routine maintenance.
