I was in best buy the other day. I noticed a PS2 that was maybe 1/3 the size of the one I have. Now, I know there is a SLIM version, but this one seems to be smaller than that. I am considering taking my PS2 and selling it at gamestop. Then I want to go and buy the mini one I saw. The question is this. With every revision of the PS2, they have always had hardware upgrades. Is there anything better with this one?
