one day, when I get some free time, I'm going to build either

or

A while back, Apple's stock price was worth less than the amount of cash they had in the bank -- I figured it was a safe bet at the time. I have been pleased, yet, I still don't use Apple, but, they sure did things right.
I don't think they should buy Tivo, but, it would be a good inroads into the home entertainment segment.
