I got a refurb rev a 2 months ago. I paid $999 for $10 for Coolbook.
Based on the relentless comments here, you would think that the machine is going to burn up, and have the hinges pop loose as soon as you open it.
Amazingly, I can do the following things with my Rev. A 80gb (hdd):
1) Develop Xcode applications, and run the iPhone simulator
2) Watch a ripped DVD iso, while holding the air in my lap without having my pants catch fire, or seeing the movie stutter.
3) Use it on my daily train commute to read ebooks, work on documents and generally do the stuff i need to do.
4) I use it as a secondary machine at work to browse, and webex meetings, while I do other things on my main pc.
Now, I won't argue about the rev.b Air being faster, supporting higher resolutions, and having faster graphics... it's all true. *If* you need those things than go right ahead and drop the extra greenbacks.
But pleeeeeez.... can we stop acting like the rev. A can't function as a usable laptop? It can. The refurbs are a bargain if it's lower specs meet your needs. I apologize for the rant... going back to work.
So you are saying it will function well enough to run an iPhone app. Honestly, Cool Book has made it almost acceptable. However the price matches performance being refurb and drastically lowered price.
My expectation with my original MBA was for it to perform like a Mac. My original did NOT perform like I expect a Mac to perform.
Since the price is high like a luxury item, it should perform at nearly same level as MB. The original wasn't even close. The new MBA performs better than a MB if buy with SSD. Hefty price for nearly same components.
The new MBA is a fully capable Mac, while the original is not. Granted Cool Book and software has helped the little engine that could. The original MBA, at time of release should have never been sold as it didn't meet normal expectations of MOST Mac users.
At least at $999 to $1299, the original MBA is a much better value as long as buyer knows about Cool Book.
I would still never advise the average Mac user buy it. For some, it will be acceptable, but we all have different usage patterns. The original MBA is not for most Mac users.
I just fully advise people to understand issues and limitations before spending over 1,000 dollars. I believe, in the long run, the rev B MBA will be able to operate properly given our always increasing demand of larger more resource intensive apps, videos, and etc.
If an original MBA works for you, be happy!
