[Richard Kimball]

a 2-3 year old Compaq is a boat anchor? It works well, not sure how it is considered a boat anchor.

You claimed the Apple is a boat anchor if it has a non-functioning battery. You then said your Compaq has a non-functioning battery.

Let's go through this mathematically:

A=boat anchor
B=computer with non-functioning battery

IF
A=B and Compaq=B

THEN

Compaq=A

WRONG! If my Compaq cost me $3000 and the computer battery died within 2 years then yes I would call it a boat anchor even if it was still usable on AC power. Do we know yet if this “Smart IC processor monitored Li-poly battery” of the Macbook Pro will allow you to run exclusively off ac power only once the internal non-removable battery dies?
