One thing I can tell you about those Apple "geniuses", most of their answers to questions like that should be taken with a grain of salt. You could ask the same question two five "geniuses" and get 5 different answers.
And, by the way, I think my use of quotation marks around "geniuses" is very appropriate.
Clearly you have only "geniuses" at your Apple store. We have "Geniuses" at ours. They are far more consistent in their answers. The capital G must be some kind of seniority ranking symbol
On the other hand "Geek Squad" has no special connotation.
