We are not carrying the G4 as we are focused on delivering what we think is a far superior product..it is in the works and we look forward to delivering in the next few months. For the moment we are working with the manufacturer to improve functionality and stability - already 4 months at this.
The decision to not sell the G4 at the moment is also based on how ridiculously difficult it is to get G4s from the vendor, that work! Too many late night calls to Asia are made to get each unit in to ship to a customer. And too little support, we have had to do support all on our own.
We would like to make sure that we are selling computers and the last batch we sold required us to do work on them before we could even ship them.
