Microwave sizes
Microwaves haven't really become smaller, they just started offering smaller sizes. You can still buy a huge monster microwave if you want one. They seem to come in 4 sizes now, full size, medium, compact, & itsy-bitsy, about the size of a toaster oven.
I hate the current cheapie microwaves that have manual timers. The original manual timers had the dial spread from 0 to 1 minute in such a way that one could set time les than a minute fairly accurately. The new ones crowd the dial so it's virtually impossible to set time for less than a minute, and setting is more critical now than then because microwaves are more powerful now and a few seconds can make quite a difference.
