Wstritt,
You hit the nail on the head. Every company, in my opinion, does just that, offers a little more for a little more. Drives me crazy. Unfortunately, it is the way of the world; cars, hotels, PC's, anything. One more bell or whistle, for just a few more cents. Oh well. Have to live with it I guess.
It does extend the upgrade path quite a bit though...:>)
