4.3 is a great update for iPad and iPhone. Biggest thing for me is getting the rotation switch back on my iPad – setting it as a mute switch in 4.2 was a bad idea, and it actually got to the point where it was affecting my use of my iPad. Strange that such a small thing should have such a large impact. You can choose whether to use the switch as a rotation lock or a mute switch in the iPad settings.
Next most important is Home Sharing. To be able to stream video from my Mac to my iPad is an obvious feature. Works well, but it needs to be easier to setup – there are too many steps to get it setup correctly for many people to bother. http://www.macworld.com/article/158415/2011/03/ios_4_3_ipad_iphone_ipod_touch….rss_mainApple releases iOS 4.3 for iPhone, iPod touch, and iPad | Operating Systems | iOS Central | Macworld
