i want Apple to make an actual iPod Stereo with wifi/bluetooth capabilities. with home sharing built in to itunes 9 it seems a simple enough task. it doesn't need a cd player in it, just a hard drive or a big flash drive. i think about 150-200 gb would suffice.
i want to be able to pull my vehicle into the driveway and have my iPod stereo sync to a "vehicle/driving playlist", add movies for the kids, or whatever from my itunes over me wireless network. no need to pull my classic in and out of the vehicle anymore to add songs. give it a touch screen double-din interface, hell even a single would be fine. have it set to sync with my iphone for hands free calling and remote. put a "good" GPS chip in it for directions. no more need for drop-down/detachable faces, no cables or docks needed except maybe to charge the phone.
i would buy one the first day it was available, hell i'd actually wait in line days before it came out.
Apple is an electronics company now, i don't see why they wouldn't or haven't released something like this.
