Technically Sherlock predates Watson, it's just a lot of the useful additional features added by Watson were copied to Sherlock.

Ah you're right, it was Sherlock 3 that copied the Watson features. Mostly related to searching the web for things like ebay listings, recipes, stocks, software.

So the Watson name was probably inspired by Apple's from previous versions, but the Sherlock 3 feature set definitely got cloned from Karelia's.
