Speaking of Bob
XP does have some Bob-like elements, such as a puppy dog that goes to fetch information. (Yes, I turned it off.)
I may have mentioned this before, but several years ago a co-worker and I went to one of these periodic computer exhibitions/shows/sales. One thing on sale was a copy of Bob. He didn't buy it, and has been kicking himself ever since (it's a collector's item, if nothing else, right?)
