Getting anxious to get my hands on the '16 MBA powering Iris 540 with 64 MB eDRAM. I've held off for many years because my 4,2 has been rock solid, and most importantly...very easy to repair. Over the years, I've had to peel back this beauty's hood and tinker to get ol' Frankenstein up and running again. I am curious how many others love their machine and throw caution warranties to the wind for the sake of cradling its motherboard like an baby. My precious is a daily grinder for almost 5 years -- Mathematica, excessive civ5, a thesis... this machine is amazing. 2011 MBA 4,2 A1369 ================== Replaced fan -- though probably could have salvaged it through cleaning Replaced SSD -- size matters? Replaced topcase -- water damage. Grueling repair... Replaced battery -- duration matters more? Replaced screws -- since all above were separate ;-p You got an old top but younger bottom? Maybe you replaced a cracked windshield or toasted brain? Please... join me and share proudly to the world how Frankenstein your MBA is!
