Think about it... When you're browsing in Safari, the iPhone is constantly checking which orientation the screen is in right? I just wonder how they could offer a feature to turn the accelerometer off in Safari and iPod. It doesn't have to be global, they could add that option in the Safari and iPod prefs. As for landscape texting, maybe they could let us choose the format we prefer in Settings first and then when we open SMS, the screen could automatically flip for you (think about the way Maps forces you into landscape mode for streetview). What do you think of my ideas. Does the accelerometer use up a lot of battery? It's hard to say because we can't turn it off to test it.
