My mother has had an iPad 2 since 2011 and now I've decided to get my dad one too. He will only be using it for web-based things (no games). I initially looked for the iPad, but these seem to be about £260 2nd hand in the UK. The iPad 2 and 3 are about £180-200. I was originally going to go with the iPad 2 as it's lighter and slimmer than the 3rd gen and charges a lot quicker. However, the 3rd gen has 1 GB memory and Siri. I wouldn't like to get him an iPad2 and then find iOS 8 will drop support for the 2. Any advice?
