It's Saturday afternoon.....
and I'm back from work, which started at 8am.
It entailed dealing with complex computer problems, such as the difficult task of inserting a CD into the drive, and opening a Powerpoint presentation stored on said disc. Oh, and I used a remote to turn on a ceiling-mounted projector.
If cars ever have any kind of user-accessible computers in them, anything more than a GPS system, people will be driving about 5mph, or stopped along the highway, begging for help, because they can't figure out that the big "ON" switch is what turns on the car.
