New here, but follow regularly. Longtime mac user but not particularly fluent in computer lingo. My 2007 Macbook finally bit the dust and I need a new computer ASAP. I'm pretty certain that an Air will suit my needs and I'm ready to pull the trigger, but it seems the wireless issue with these machines has not been resolved, even on custom built recent issues. My question is: Is this problem software or hardware based? Meaning, is there any chance that I'll get an Air and the wireless issue is something on the hardware side and won't be able to be resolved without replacing hardware or the machine itself? I'm fine if it's a software fix that they will be able to resolve in time with updates, but something irks me about buying an expensive new machine that is likely to be flawed on the hardware side.
