Well, I am happy with what I have got. I won't bother to download or install Yosemite. I am in my mid-70s, and will just hope this computer lasts long enough to see me through until I abandon the internet for good.
Dude/Dudett I have a few more years on you thats all. At 74 my next birthday my take on the world is somewhat dim. All that texting, all that electronic craziness, groups of people jumping up and down applauding silly nothingness. What happened to rational value, things that just plain worked and did not need changing.
No need to abandon your computer, if it still feels good and your up to it, then fight out another round or two. Time is not on our side after 70 so try to get the best out of everyday. Your in the autumn of the life cycle, and sooner than you expect the cool winter winds of winter signaling the end game arrives.
