No new computer

What will it take to convince Stephanie to buy a new computer? Well I sure don't know. Our old computer is old, as in given to use five years ago when a family member bought a new one, old. We've tried to beef it up with more memory, a flash drive, and some other tinkerings. It is still extremely slow. So slow I can hardly stand to do anything on it. I use the computer at work. I try to tempt Stephanie every now by showing her an ad. It really would be a practical purchases, as much as she uses the computer. But she doesn't budge. Hard headed like her dad!
