My electric toothbrush has bluetooth. How much free time does someone have to track and analyze their toothbrushing?
Sticking it in a toaster reminds me of when LCD clocks first came out. They stuck them in EVERYTHING. Even table lamps had little clocks stuck in them. Then when LED lights came out everything had to have super bright led lights all over them. One to show you it was off, one to show you it was on, etc, etc. Same with everyone had to have a website in the 90s or a mobile app later. Now everything has to be connected to the internet because, well they can. There is no real reason for it except marketing.
