My cousin (in her 60's) has a computer - her DH won't touch it with a ten foot pole.. No interest at all..
A 70 year old pen pal had Web TV for awhile.. Gave that up and decided she was not interested in having a computer.. (She works on one all day long at the Post Office..) However, she recently purchased he son's used lap top and is very quickly becoming frustrated with it.. She only "allows" herself a half-hour per day to use it or learn anything on it..
DD's FIL (mid-to-late 60's) has had a computer for a few years now.. He just decided this week that he needs to take an introductory class for Windows XP.. I don't know what he's been doing with it up until now, but I do know that his wife (same age) is terrified of it and won't have anything to do with it at all..
I got my first computer (used) in 2000.. It was Windows 95.. I learned most of what I know by trial and error.. Considering it only cost me $120, I wasn't too concerned about blowing it up - LOL.. (My late DH had NO interest in it at all..)
My second computer was Windows 98SE - used.. Again, trial and error..
The lap top I have now I purchased in April of 2006.. I'm not so quick to fool around with the "trial and error" stuff because I bought it new and it cost me a nice chunk of change.. However, I did purchase used copies of "Windows XP For Dummies" and recently, "Cleaning Windows XP For Dummies" and I use those for guide books a lot of the time..
My mom (90 now) never had any interest in having a computer and never would have been able to figure out how to use it in a million years..
I know a lot of couples (older) where there is a computer in the home, but it's usually only "one" spouse that uses it - not both..
