Upright toaster is very quick and low risk of burning even when left unattended. I my experience, that timed example falls apart unless you're right there to take it out of the oven. I don't drink coffee so have no reason to hang out in the kitchen. I'd start it then go to my room and get dressed and return to my toast on my own time. However, my toaster oven behaves like a real oven and holds heat even when the elements turn off, I'd have to do a lot of experimentation to figure out the right time/temp setting. Figuring out the desired setting on a upright is incredibly easy. Once set, it's set and forget. You just push the button, walk away, return when you want to eat your toast.
