I have asked a similar question before but our situation has changed and we would appreciate some guidance. We have two Core 2 Duo MacBooks at home which we want to be able to back up wirelessly when Time Machine is released. We also want wireless internet and AirTunes. Wireless printing would be advantageous but not essential. It is worth bearing in mind that we have a modem that doesnt work with Intel Macs. I dont know whether it will work with an Airport base station that is connected to an Intel Mac. Now, it seems to me that we have three main options: 1. Airport Extreme and external HD. Pros: should be fast. Also supports wireless printing. Cons: no AirTunes, all-in-one means we will have to keep the external HD and printer near a phone socket. May also need to buy a new modem. 2. Airport Express and external HD. Pros: supports AirTunes and wireless printing. Cons: cant see how we could back-up wirelessly. May need to buy a new modem. All-in-one means we will have to keep the external HD and printer near a phone socket. 3. Somebody has suggested that a wireless server may solve the internet and back-up problems, but I dont know how much they cost, what they do, or whether it might be difficult to sync with Time Machine. Not knowing much about option 3, the second seems most sensible, since in choosing option 1 we would be paying quite a lot of money to gain wireless back-up but lose AirTunes. Any thoughts? I have been trying to solve this for months!
