I would love to see your statistical (or any other factual) support for this assertion. The number of Airs (version A) sold versus the number of complainers on a handful of Apple oriented message boards? I really do not think we are talking "MOST" here. I'm not defending Apple, if the product has problems, it has problems, but your bald assertion to try and win an internet argument, simply strains credibility.
OK, I'm a Rev. A lover, I have problems with core shutdowns now and then, I would love to upgrade to Rev. B, but hadn't the bollocks to do that.
But I can tell you something:
Here in Brazil, I know precisely five Rev. A owners other than me.
All of them sold their MBAs and bought unibody MBs when they came out.
All of them complained a lot about the heat and core shutdown issues, and all of them patiently wait for Apple's updates, and gave up after seeing not much improvement on that.
All these guys would never come to a forum to post complains. Never.
Looking and Mercado Livre (which is eBay for Brazil), you'll see like 15% of the MBAs there are Rev. B. All the rest are Rev. A that are hanging there for months. That's because the MBA is seen here as a pricy flop.
I'm a huge fan of the MBA, but no one believes me when I say it's a great machine. No one.
Sad, but true.
So, it's not a scientific or representative measure or anything, but the fact that Apple ships thousands, millions of machines and we only see a handful of users complaining at boards doesn't means they're not having issues.
In fact, I never saw any refurbished Apple laptop get so big discounts like the Rev. A is doing. That must mean something, don't you agree?
