I am recently in the very fortunate position of having $1100 that I need to spend in the next two months on an "education related expense" which basically means laptop for me and since I already have a 2012 MBA I love I thought it would be great to upgrade to the 2013 MBA which I expect to be exactly like my old computer except with wonderfully amazing battery-life. However checking around Apple's support forums and a few reviews (mainly Gizmodo) I'm a little concerned about the Wifi performance. I know that Apple is using a new faster wifi standard (which I could care less about because the chances of me encountering a router using this new standard are next to zero). What I do care about is compatibility with older routers. My home router is fairly new (bought a little over a year ago brand new) so it should be fine. But I also want my MBA to work at coffee shops and at work where I can't rely on others to have upgraded their routers or change router settings. So my question for current 2013 MBA owners is this: How is the Wifi performance. Any issues, especially with using the MBA on wifi away from home. Should I be concerned? Thanks in advance!
