Actually I am
trying to think of anything I own and depend on (or
even use actively) that I am not capable of repairing....
Your PC's harddisk,
Tony doesn't have a "PC" (he's stated this often enough that even I
have managed to remeber it - even if I've misremembered, I'm quite sure
he does not "depend on" one) and quite likely does not have, and surely
does not depend on, a modern "harddisk" - by which I mean one with
effectively unrepairable electronics (by heavy dependence on
undocumented ASICs) and a sealed and approximately unrepairable
head/platter assembly.
Also the same is true for the computer CPU's.
Not for most (all, probably, given his statement) of Tony's machines.
You do not want a FIB machine so you had a chance to
repair the IC
itself.
This too is quite likely not true of Tony, I would hazard a guess -
possibly excepting reasons of physical space.
