you might want to go read some of the other articles. Apple "Record quarter" was not a so much of a record. It missed it target on a lot of sales.
It record came from the fact that it changed it accounting recording so they got a one time boost in the numbers from all the money they had set aside before hand. Accounting rules changed. They did not announce the change and let the press and apple fan boys run wild with those huge numbers. Go read on the other articles on Betanews that point out that little tide bit.
If the numbers are too good to be true chances are they are. I question this 90% number. It seems almost to good to be true.

Apple sold a record number of Macs. We're not talking about revenue or profits, or accounting. Unit sales of Macs were the highest ever. Every quarter Apple sells more Macs. So we have an upward trend on a group of products that are $1000+. In a recession. In the presence of lower-cost options. That's what's pretty mind-boggling.
