Granny isn’t sure she really wants a computer, so she buys the cheapest PC that Dell will sell her, with barely enough memory to load Windows XP.
Granny doesn’t like spending money on things she doesn’t understand, so she has her friend install a free antivirus scanner, the side effects of which are not much better than a full-blown spyware infestation.
Granny wants to use her computer to share pictures and print boarding passes, so she installs a bunch of bloated, buggy software from Kodak, Hallmark, and HP (because installing your printer drivers should take 3 hours, otherwise how do you know they’re good?).
Granny doesn’t know what’s so great about computers, anyway. They don’t work very well.
