Powerlogix has finally made available the G3 upgrades for the Pismo's. Available as Vari-speed 800 Mhz ($299) and 900 Mhz ($349). G4 500 still available. It is now very tempting to upgrade as my Pismo has been completely trouble free and in my opinion is the best laptop design Apple has put out to date....not the fastest but great design and expandability. Now the question is G3 or G4?
