Howard, I'm 58, my eyes not so great anymore & from the onset, soo as I laid eyes on it, the 1st thing that impressed me about Office 2010 was how EASY it was to see everything, felt serene (in a way), just more relaxing to find & SEE things.
As for you equating cars to Operating Systems... what you are saying actually does apply (ironically enough) to XP not Windows 7... IT was, indeed, a couple yrs & or a couple Service Packs before XP really had its act together (& still keeps needing patches & security updates)... as opposed to W7 that has its act together right out of the gate.
