Re: 
I was referring to what is readily available for slots. While it is true that you can replace the memory chip behind door number two, I don't know if that will do anything to the warranty. The towers have three slots, and if both the iMac and G4 tower ship with one chip, you can still add two to the tower but only one to the imac.
For the extra storage in the iMac, unless you want to get into the guts of the system, you will have to go with external storage. With the tower, you can put a total of four drives inside it (including the ones that ship with it).
Either way, get what you can either afford, or really need/want to. Either way, just go smart, and get a Mac

I agree with everything except this point; I see no reason why could can not add 2 memory chips and extra storage to the iMac later on... they are both possible, just not user installable anymore (minus one RAM chip).
