My wife has an iPad mini 3 that she uses primarily for mail and web browsing. I was thinking about upgrading to a 5 for her in the hopes that she would see some significant speed improvements, but given her use I'm not sure if it is worth it. So 2 questions: (1) should the mini 5 be a good bit snappier than the 3 for web browsing? and (2) Assuming we go ahead with the upgrade, is there any reason to wait for a possible replacement (I assume not as it hasn't been out that long) or maybe until later in the fall for possible sales?
