It seems like people really got their hopes up REALLY high about Woz. A new company with big ideas! I'm in!
Maybe Jack's fault, maybe most people just wanted something new/different.
When people get huge expectations about a product most will be let down no matter how great the product is.
People do this regularly - new cars, new golf clubs, new phones, new girlfriends.
I also had really high hopes for Woz, then realized it is hard to make a totally different/new game changing item that has been around for 80 years.
