They consist of a variety of machines. I like all of my machines to be consistent and synchronized with each other so that, in my roaming around, they will all appear the same. I utilize business class Roadrunner, and at home residential Roadrunner, isync and .mac to accomplish that portion. I began with my lowest configuration, an imac 333 tray load, first. It is used by my hostess/ secretary, at the door, to log in customers and their broken equipment using quickbooks pro 5. It has preformed well since the beginning OSX and is now at X.4.3 . Next came the BW 400 and the rest followed shortly there after ( Imac 500 and 600 DV's , AGP 400, QS 867, and both MDD Firewire 800's). All of the machines have their own list of jobs to perform and are relied on heavily to do so. I use a variety of hubs, switches, and routers to maintain connectivity with each other , three printers, the internet, and my iDisk. I have absolutely no complaints so far with Tiger, so far that I can blame on it anyway. All of my machines have their own character and flavor. Of the few bugs that I have had down thru the line of OSX , the next update was there to fix them before I was even sure what caused them. Go ahead, Jump . It is a nice landing .
