Watching regular people try to use technology is so painful.
The other day I helped a man in a cafe get dictation working on his new MacBook Neo. It took three of us (two very technical) 10 minutes to figure out.
We had to turn OFF Siri so that the F5 button would enable dictation in the way that he wanted. We then had to coach him on the difference between tapping F5 to toggle dictation on and off as opposed to holding down F5 constantly.
And Apple are meant to be good at this stuff!
