I set it up last week, covered this morning and shorted again. I've run into a number of articles questioning Apple's performance numbers. It was a trickle about 1.5 weeks ago and now many articles have come out about it. I usually link to one per day on my blog.
I am a newbie on AAPL stock as well but I'm a user, I read the forums and I do assembler programming on Power and x86 and you'd have to be skeptical about a 400% performance improvement claim from one chip to the next.
It is way too easy to slant benchmarking results these days.
