Hi, so, are there only these two known issues with new macbook air? 1. WiFI problems - dropping connections and switching to n instead of ac after sleep - can anyone running Mavericks developers preview confirm this problem is gone with Mavericks, or not? - or, if anyone with new MB air participates in that voluntary apple seed program, does that tested update resolves the issue, or not? 2. display flickering with some applications (adobe PS, parallels, vm ware) - again, does it occur under OS X Mavericks? Simply, can anyone confirm this is just SW issue that will be easily solved, or it may be HW issue and my potential brand new mb air will be crippled? Are there any other known issues?
