Although I had switched over to Windows by the time of the Pismo G3/500 (voted the best ever), I had my 540c upgraded with a PowerPC, and got many years of delightful service out of it.

I had a 5300 for a while and it was a piece of crap compared to the sturdy souped-up 540c.

It had two big symmetrical removable battery compartments, so you could switch out one at a time and keep running on as many batteries as you have pre-charged without interruption! Plus there was an external dual battery charger.
And you could swap a hard disk drive or CDROM into one of those bays.
Plus it was fat enough that it was able to cool so it didn't overheat all the time like an MBP.
Anorexic thinness isn't a thing for me: I'd trade a lot of thinness for huge removable batteries and great ventilation.
