Scottsdale.. first, I'd like to say that I really enjoy your posts. Intelligent and insightful.
As far as the MBA Rev A goes, I have to disagree. I upgraded mine with a Runcore 128GB SSD and it is more than an acceptable machine.. in some cases, quicker than my late 2009 Mac Mini. BTW, mine 'Just Works'.
For Office apps, internet, email, Photoshope Elements 8 & Adobe Lightroom 3, watching movies (mostly those that come packaged with BluRay's), streaming music, it is more than sufficient for light duty work and quite a pleasure to use. I do admit that it can get a little warm at times.
I do however agree, that with the 80GB hard drive, it's painfully slow.
I'll probably use my MBA Rev A until it dies. So, if you can get one for 'free' 🙂, or relatively cheap, adding a Runcore SSD is a no brainer. (if you can do both for under $1,000)
Back to the OP's question.. would I buy one now? Given today's technology & prices no, unless I could get a screaming deal on a Rev A with an SSD and weight is a major factor. I'd do a white book or an MacBook Pro 13.
That is your opinion... we have differing opinions.
PATA drive controller doesn't even allow full bandwidth of the Runcore SSD.
Limited drive space.
Intel graphics that are as bad as day one... no improvement... the v 2,1 gets graphics, OpenCL, OpenGL, and h.264 updates with every OS X update. It has gotten better and better.
Merom CPU that is too hot and been problematic since day one.
667 MHz RAM that doesn't match what the 2,1 has to offer.
A POS Mac that doesn't deserve the name Mac in any way... If I were Jobs, I would feel like a thief selling that POS to people as a Mac. The most disappointing Mac in the last five years, bar none. Not even close. Absolutely disappointing and worthless.
The original MBA looks pretty, but in just about every other way, it's worthless. Sure you can check email and surf the web, as long as you don't want any interactive media or videos, but all in all it's basically a writer's computer... basic as can be.
The 2,1 MBA is a real Mac. It gets better and better with every Nvidia, OpenGL, h.264, and other driver update... it has been shear joy owning several 2,1 MBAs. The original was a joke from day one, and Apple should feel bad for selling such a POS... the proof was what it did with the pricing... dumped them from $3099 to $1299 in less than eight months... $1799 to $999... and the biggest proof that even Apple thinks it's a POS is the fact that the rev 2,1 changed EVERY MAJOR COMPONENT/Advantage. CPU, GPU, drive, drive controller, RAM, MDP, and etc.
I am done giving Apple a pass on its worthless POS original MBA. It is amazing the MBA brand is still here. Apple f'cked so many people over, and destroyed the brand so badly that it should honestly axe the MBA and call it something else with its next update. It is obvious that Apple doesn't care about its customers too, and I am done defending that jerk SJ who would sell such a POS garbage machine that doesn't even deserve an "eMachines" branding on it. It looks pretty, but other than that, it's worthless for anything beyond email and Microsoft Word.
