Don - I'll bet your wife and mine share a common interrest (or LACK thereof)
I'll bet you lunch that your wife couldn't tell you the model number of your keyboard, or even the brand ... unless she sees the box in the garage all the time.
My wife has NO clue what I use at work, and if I replace it all tomorrow - she's never know the diff.
She's often said that I better have price tags on all of it for when I die. That way she and her new husband can sell it all easier. The business dies with me, I'm afraid .... no one wants to carry the baton.
