When Apple has their Quarterly press conference expect the iPad 2 to list 4+ million or more sales with back orders in the millions.
The return rate of all Apple products, across all of their hardware lines are lowest in the entire industry.
The iPhone 4 fiasco had a return rate half of that of the iPhone 3GS that everyone loved.
iPad return rate is at 2%: http://news.cnet.com/8301-13579_3-20030211-37.html
Look to that being at or lower for the iPad 2.
Ummm - the reason probably is shown on the 1400 post "light bleed" thread. People WANT the thing bad so they don't "return" it... they get it "swapped". Quite a few people over there are on their 4th to 5th swap
(which boggles my mind frankly) in a search to get one with no bleed.
They all seem to have it to varying degrees but I have to hand it to Apple for (so far) not claiming this is "in spec" to shut down all these
"swaps".
Apple probably lists all these as "exchanges" and therefore they don't count as "returns". Makes the customer happy and makes them look good in the press. Everybody wins.
Towards the end of the huge thread over at Apple.com people are being told the same thing from the reps when they call... that Apple "is looking into the qc issue on this batch of iPads and hopes to resolve the issue". That's good news for everybody.
