> As for microwave ovens and other appliances, if updating software is not a normal part of use of the device, then it is not a computer. In that case, I think the user need not take cognizance of whether the device contains a processor and software, or is built some other way. However, if it has an "update firmware" button, that means installing different software is a normal part of use, so it is a computer.
That... Doesn't make sense. What if the "button" (probably a jumper or connector on the motherboard) isn't normally accessible to the end user, like a lot of embedded devices? If it has a CPU, ROM, RAM and runs code it's a computer!
