Should have got her an iPad. After years of trying to keep my mother on the straight and narrow with the likes of Windows (and yes did dabble with alternatives) I gave her an iPad, and my quality of life (and seemingly relationship with her - why can we be so patient with strangers but not our own relatives, one of life's big mysteries) was considerably improved. The worse I ever had to do then* was talking her through a webpage and I knew exactly what she could press, no.more right clicks by accident, double clicks by accident nor design. I weep tears for our lost years in the wilderness of PCing her.
But seriously if you have er.. damn I can't really say elderly any longer, a less technically able person, such as an parent or a teenager get them an iPad (and one of the cheaper ones), you'll be thanking me.
*Actually there was still a soul destroying support issue: printers. IPads seem designed to not print, persuading one to connect to a printer involves an arcane ritual that requires the blood of a virgin, a phoniex feather and the use of the holy grial and let me tell you getting hold of one of those 3 items is damn difficult.
