Comparing closed firmware with general purpose OS is bogus

I dislike Tannenbaum's (and other's) references to TV or DVD players. These devices are closed, fixed, firmware. I never heard of any user installing software on any of these.
Well, one could hardly imagine a PC on which you cannot install any additional software: any buyer?
Now many of the problems people have with computer is application setup. Looking at the Tannenbaum's list of OS recommended feature, I do not see how he addresses any of these.
If my text processor dies and minix has restarted it, what about the 300 pages document I typed? Of course, good text processors maintain a recovery log on disk, but that is a design of the application and the OS cannot take credit for this.
Mr Tannenbaum has a (OS) hammer, and anything looks like a (OS) nail to him.
