Just testing a theory ...
To those who don't mind responding:
Answer each question below once for each user in your organization and add to the running totals (so every reader of this discussion doesn't have to add them all up).
1. Do you PRIMARILY use a Mac or a PC?
2. Are you right-handed or left-handed?
So, for myself, although I use a Mac and a PC, and I use my right hand more than my left, I'd answer
Therefore, the current the running totals are as follows
Mac & Left-handed = 0
Mac & Right-handed = 0
PC & Left-handed = 0
PC & Right-handed = 1
