First i want to say that i have followed this forum for severel weeks so thanks for all the tips and tweaks! This is my first mac,im not "leaving" windows,actually im very satisfied with Windows 7 and didnt have any problem with vista or previus ms OS, im not a fan boy i really don't care what OS system i run just aslong as it fits my needs. My needs are ,writing,internet,music,videos and hooking it up to my samsung 1080p. So after reading in this forum,everybody seemed to advise NOT to buy the macbook air rev:a so my search began to buy the reb:B refurbished but since they are very expensive in sweden compared to the states i found a refurbished macbook air rev:a for 974$ with the optical drive. Its in mint condition,never left the house and the battery has run only 30 cycles. This might sound overpriced but please remember that in sweden this is a very good price since apple doesn't sell refurbished mba here. I was very concerned since so many issues has been reported about the mba reva,"overheating core shutdown,lines,hinge cover and ticking hd noise." Fortenelty my mba has not suffered by any of these issues(at least so far . I bought coolbook witch i regret since i haven't even needed to use it. The max temp has gone up to was 70C while it was connected to my tv,running several tabs with flash content in safari and msn. My idle temp is 38-52c 1800rpm. Playing 720p content from apple trailers works perfect also tried a 720p mkv sample via plex with no problem(the ones i have tested so far). 1080p video lags of course. I have played hdtv rips like lost in plex for longer periods and the temp reched max to 65c. some you tube clips has had "hiccups",not all. Many claims that the reva is slow,honestly i feel the opposite way..maybe people have unreasonable expectations?remember its only 1.6ghz with 2gb ram so don't expect a Ferrari. Well i have been using my mba for a week now,its not perfect but so for i love it. There are some stuff in the OSX that i don't like such as cant maximize safari,pathetic that i need to install an add on to maximize a browser. So for im pleased with my mba reva,i hope this "review" help anyone also sorry for my bad english =) So how does your mba air rev:a 1.6 80gb perform?
