My mother bought an iPad at the age of 67. She's not remotely technical - before she got a mac, I'd routinely get support calls of the quality "help! microsoft isn't working!", where 'microsoft' meant anything from Word to a browser to, well, anything. Anyway, the ipad was used for about a month, then plonked on a shelf to gather dust as she went back to her macbook.

As a naif and something of a technophobe, she definitely did benefit from moving from Windows to OSX (back in the late XP days), but iOS left her cold.
