I was thinking more of the battery in the original Mac Portable (which  
I know is not what you're referring to).  The portable weighed 16lbs,  
due in no small part to the lead-acid battery it used.  I guess it's  
technically not a laptop, but it was definitely not in the same class  
as, say, the Compaq portable. :)
