Sonnet Tech just announced a G-4 1Ghz upgrade for the Beige box last week they are supposed to come out with a later update for the B&W which is what I am looking for. The only draw back is that it will set you back $700 dollars just for that upgrade. I think you could get more bang for the buck if you spend your money like Scott suggested then on this one item, but at least the flexibility is there now if you find the need. I bought a dual 1.25Ghz from the latest crop from Apple because I just got tiered of weighting for such an upgrade, but I still kept the B&W around. I am using it less and less.
