Apple has been choosing bargain basement PC parts for quite some time now, the shame is people are paying for quality and not getting it anymore.
With all the security issues lately, Safari, WebKit, iOS numbering over 100 exploits in the last two patches alone, AT&T security issues, etc. The App Store lockdown, the closed machines, Flash-less, crippled iPads etc.
I'm not seeing a good enough reason to pay thousands for a laptop from Apple when a Ubuntu Linux laptop would cost a few hundred and provide excellent security for all my netbook needs.
The new Ubuntu release is excellent, any Mac user could use it fast. Tons of free software, Flash and Firefox is a great browser.
You're citing lack of Flash and Firefox as a reason for not buying an MacBook?
Not only is that ridiculous, but you're kind of off topic for this thread, aren't you?
From the reports of users with the yellow screen, it does sound like the glue/adhesive could be the culprit. That's good news.
As for the antenna issue... I'd be curious to know how many units this affects. My guess is only a couple of production runs. But that's a guess.
