Just wondering : how's the performance of the latest Beta of iOS7 on an iPhone 4S and an iPad 2 ? Definitely would like to upgrade my iPhone 4s from iOS6 to 7, not sure about the iPad 2. My wife and kids use the iPad 99% of the time and we will be buying a new iPad (either 5 or refurbished 4) somewhere around Christmas for my wife, passing the iPad 2 to the kids. So very curious about performance on the 4S. Anyone ? Just bought a mid 2013 Macbook Air and will be upgrading to Mavericks quite soon if all my software works so would really like to have iOS7 on my iphone. If the performance on the iPad 2 is good, might as well upgrade that as well.
