There doesn't seem to be much news on MBA updates. I am thinking of getting my wife one for Christmas. Are there updates coming that are going to be must-haves? She doesn't know Broadwell from Snackwell so I don't think a new chipset is compelling. Retina displays maybe, but even that wouldn't really do much for her if it makes the thing a lot more expensive. So are there must-have updates from a basic user experience coming?
