The 7000G is a similar colour scheme to the 4000P, just with a bigger screen for the graphing capability and with rubber keys.

I'm actually quite fond of that series of graphing calculators. Still on the look-out for a 6500G as I already have several 7000G/GA/GB machines, a couple of 6000Gs and 7500Gs, an 8000G and an 8500G.
