I also work with other people who travel as much as I do and I don't ever remember any of them mentioning theft from baggage, we all carry high value IT and other equipment as well.
I think the incidences of theft from baggage is one of those things which is assumed by the public to happen très souvent but in actual fact is extremely rare, or is in my experience.
The airlines and airport operators are aware of the perception of the public and do everything possible to prevent theft from bags.
