I am 99% clueless about this kind of stuff, so I have a few questions, grateful if anyone can answer. 1. What is the difference between airport express and airport extreme? 2. Can both routers set private/public ports for port forwarding? 3. What benefits are associated with using an apple product (e.g MBA or MBP) with an airport router? Are there any integration features? 4. Is Time Machine better than both the airport extreme and airport express? If not, in what ways is it inferior/different? 5. Is it possible to plug a usb memory stick to the back of an airport extreme/express and have it function as a network drive that anybody can store files on? 6. Is it possible for the time machine to use its 2TB/3TB storage as a network drive instead of having to use it for backups? If backup size does not fill the data limit of the time machine, is it possible to use the rest to store shared files? Is it possible to partition a certain amount of the time machine's memory to become a shared network drive? 7. What are the advantages of using Time Machine/airport with an apple TV? Is it optimised for AirPlay? 8. Is it better to use a netgear/linsys router with a PC or is airport optimised for both systems (perhaps with some bonus features for mac users)? Thanks in advance!
