Hello, I'm thinking of purchasing an Airport Extreme Base Station to replace my linksys 54GT, but have a few questions that hopefully can be answered! 1) Is it smart to buy one now, i.e. will a new model come out soon? 2) My plan is to buy a USB hub and I want to have 2 hard drives attached and a printer. I want one of the hard drives to be for time machine, and the other to be for sharing. Is this possible? 3) Any alternatives that will let me do the same stuff??? Thats it! any help greatly appreciated!
