why can't these computer businesses get their stuff together...

'Cos they don't care.

When I studied compuer science we were told "If your program doesn't work, don't bother turning it in 'cos you'll get an F"

And "if it brings the machine down, don't bother coming back for the rest of the semester 'cos you've failed the course"

We were taught to write programs that worked. Doesn't happen nowadays.
