i want to be able to watch movies off of my external hard drive wirelessly and i think the airport extreme is my best solution. i do have a few questions, however. 1) will the extreme have enough bandwidth to support wireless movie watching without lagging. 2) i noticed on the apple website that if you want to do wireless printing your printer must support this feature, but isn't all the printer needs is a usb connection? (i have a HP Photosmart C4480 if that makes any difference) 3) is there a cheaper alternative to the airport extreme, obviously i'd like to save a few bucks if possible.
thanks in advance!
