I own a G40 All In One desktop. I love it very much. If you could upgrade it with a new processor, and all of the other new and cool technologies that Apple has pioneered or used in their newer desktops I would do it in a heartbeat. BUT you can't and that's that! I see many, many posts on Computer forums such as this one by people asking questions about upgrading their G4 and changing processors and trying vainly to modify their G4. If Apple made a Retro model G4 that looked exactly like the original G4 except for the color or some new visible model number stating it as such. I truly believe many thousands of people would purchase it. (I mean how cool is that Round Apple Shaped Base Case and the Swivel Monitor) C'mon guys and girls, I really mean it! The G4 is truly an admired piece of equipment.
