iPad Dis-Orientation

Just before selling my wife’s iPad to upgrade to a 3G model, we updated to the 4.2.1 iOS.  Here’s my review:

Love the folders.

Love the multi-tasking.

Love the AirPrint capability (once we have a compatible printer, or make it work with our wi-fi Brother HL-2170).

Hate, hate, hate the repurposed button on the side which used to control orientation lock.  What was Apple thinking? I’m okay with making the functionality a user option, but to make that a mute button means that there are now two buttons on the side of the iPad, BOTH of which are effective at muting the sound on the iPad (hold the “down” volume for 2 seconds and it goes to mute).

Anyone have insight as to what Apple’s rationale was on this one?
