You can get ones with temp probes and other silly things but... it's a multimeter!! what you need a temp probe for on a multimeter!!!
I think a temperature probe could be handy in certain situations - perhaps you're running a stepper, and its getting warm, and you want to know whether it is running hot enough to need a heat-sink (same perhaps for an h-bridge). Could provide some data to plug into formulas to see if you are exceeding a certain temperature loading on a MOSFET or something.
I'm sure there are other similar uses in electronics - and there are certainly uses for temperature readings when you are doing other things (perhaps you are measuring the voltage of a solar panel and -ouch- its hot - but how hot? etc).
