I have had my refurb Rev A for almost a month now. I am really happy with it, my needs do not differ much from yours though I haven't tried iMovie on it (I deleted it right away as that's one of the things my 24" iMac is for.) I did spend $10 on CoolBook and $8 on Arctic Silver 5, not sure if I had to or not, but it certainly didn't hurt. $18 is a little easier to swallow than an additional $800 for a Rev B. Although it isn't my primary computer, I have been using my MBA everyday and am completely satisfied with it. I have been streaming movies from Netflix with zero problems. The battery was new, and I am typically getting a solid 3.5 hours out of it. Other than the different serial number, I couldn't tell it was a refurb, looked flawless. Right now I have been on it for about 2 hours, have been streaming pandora while surfing, watching a few videos from various news sites, and am sitting nicely at 49C. My recommendation would be to go with the refurb, and worst case scenario, if it doesn't work out, you have 14 days to send it back to Apple and get a Rev B. Technically there is a 10% restocking fee, but I'm sure as long you let them know you want to upgrade and the Rev A isn't meeting your needs, they can waive that fee.
I am with the others in not knowing what Scottsdale's problem is with the Rev A. If you look through his posts you will see that he had a Rev A, which he sold to get a unibody MB, stating he only used his MBA once, when he first got it. Later on he says that he installed CS3, Windows, and Office on it and it ran them just fine. So I am just as confused as everyone else. The Rev A may be an inferior machine as he says, but it certainly isn't $800 inferior.
I would pull a Colbert and take everyone's suggestions with a grain of salt, and go with what your gut tells you. Either way, the MBA is a hell of a machine and I think you won't be disappointed with either.
I had a 2.33 MBP before a unibody MB. I owned the MBA rev A while owning the MBP. The original MBA wasn't even useful as a secondary computer. I tried it for two weeks but every use was a disappointment. It was extremely slow. I couldn't do normal tasks on it. Even working on a few apps lead to extremely slow computing. The only thing it did well was email and word processing. I agree Cool Book and reapplying thermal paste helps. So does software rewrites.
The absolute game changer is the rev B MBA. It does everything as a primary Mac. It replaced my unibody MB and my MBP 2.33 GHz.
You think the average Mac user would want to reapply thermal paste and learn about undervolting? Takes a special person to want to go that route. Takes someone who really wants to save some money.
If you can make an original MBA work for you, great. But I don't think it's for most Mac users.
The bottom line is 20W Merom with Intel 3100 creates a lot of heat for the tiny confined space of the MBA. The 17W Penryn with Nvidia GPU has really changed the problematic Air.
I wish as much as anyone that my original MBA would have been even half the computer as the rev B MBA. Not that I wanted to blow a bunch of money. That is not what it is about. As much as I tried to like it, and as much as I wanted the original to be my primary Mac, it was NOT fun. The rev B MBA was everything I expected the original MBA to be and more.
I think as Mac buyers, we should all get what we pay for, and I don't think the headache and hassle of the original MBA is worth it.
The rev B MBA just works. It works for everything I can throw at it. And it is a faster Mac than older 2.33 MBP or even a 2.4 GHz unibody MB. I know that is the SSD, but it sure is amazing.
My rev B MBA was stolen, along with MBP, ACD and etc. Was a bad loss.
No matter what, I am not going to go buy a rev A MBA. I would recommend any other Mac from the last three years over the original MBA. And for most people, I would recommend they consider the rev B MBA if they want portability yet amazing speed and performance.
I believe being harsh on the original MBA is acceptable. It's not like I made this crap up. Most who were original buyers experienced everything I have complained about. This is widespread common knowledge. I think anyone that is considering the MBA should fully know and understand the differences. If they want to buy the original MBA more power to them. Would I spend my money on an original MBA? Never again at such a high price. To me, the rev B at even $1000 more is worth the price. For most people, as a secondary computer the original MBA would work providing they learn and install Cool Book and many need to reinstall thermal paste to lower the CPU temperature so the MBA doesn't sound like a helicopter with its fans on full blast during normal use.
I will say that for those willing to work with the solutions of the original MBA like Cool Book, they can have a really beautiful MBA that is ultra portable. I just don't think it would be a good primary computer for anyone. At the same time, I think the rev B MBA makes a great primary computer.
Also, comes down to future capabilities. Right now the original MBA has been reworked to run without all of the problems. But, it still has an overheated 20W Merom CPU. It still has Intel 3100. It still has a PATA drive controller. It still has slower RAM. In the long run, I think the rev B will be a much better solution. Software routinely gets updates and people demand more and more from their computers for media and entertainment purposes. That means they use bigger and bigger files. While it is acceptable for some now, I fear the original MBA will be a bigger problem down the road. While I think the rev B MBA will shine.
Lastly, could an original MBA run intensive software, YES ABSOLUTELY. But it is very slow. From its 4200 rpm PATA drive to its slower clock speed to its lower cache size to its slower RAM. For me, I could not deal with it when I had an original MBA... but those things would run if willing to wait out the processes. But for the most part we are talking minutes and not seconds.
Maybe I had a really terrible original MBA, but with all of the complaints, I have to imagine my experience was the norm.
Has the original MBA changed? Absolutely, I recognize that. I think I have been very fair to the original MBA since learning about Cool Book, software rewrites, and reapplication of thermal paste has helped. But for MOST MAC USERS, I still recommend the rev B. If for not now, for the future.
But if someone only has a $1000 to spend, and they need a secondary computer, and they want it to basic tasks, and they plan to install Cool Book, and they plan to reapply thermal paste if it runs too hot/loud fans, and they buy Apple Care... SURE
And by the way, my six year old Dell Inspiron plays streaming video from Netflix. I don't think that is a measure of anything. Nor is ten minutes of video on the rev A MBA.
I actually have a Dell laptop from 2001 that I found in my garage, and it runs about the same way I remember my original MBA ran as far as speed and performance. That is really a serious comparison of speed and performance that I noticed with my original.
