I really don't see integrating wireless capabilities as a value added feature. It will increase costs for no reason. Or maybe I just underestimate its value/appeal, but as a customer it's not something I am looking for or want.
I like Microsoft's current approach...adding value rich features through software updates. Also, hopefully with increased 1) reduction in hardware components, 2) efficiency and reliability in hardware components we will see a slim model within a year.
I do wish Microsoft would allow more flexibility with external hard drives. That would be nice.
I'm not a fanboy, I just try to tip the balance in favor of logic and common sense.
