Regarding the long press for enabling/disabling wifi, etc., I know I've mentioned this to +Ron Amadeo
before but it's the difference between a common, high-level feature that a lot of people use (airplane mode) and a power user, low-level feature that isn't meant to be part of a common usage pattern. (Toggling individual radios on and off.) Switching networks or selecting one in general is meant to be far more common than twiddling radio power, so it's given the easier access.
The power user community has, predictably, disagreed with this decision. ;)
