What if...
Apple was concerned about comptetion so it updated the iPad to iPad 2 before any o the others got off the ground.
Then they wait till July to see how the bulk of the competition does and how much impact, if any, apple feels.
Then sept timeframe they realease iPad 2 upgraded model to combat wherever the competion is really and truly smacking them. Most likely in screen resolution, camera and ios 5.
Just a thought. Unless apple ha another trick up it's sleeve which will get introduced with ios 5 that somehow improves the cameras capabilities.
Just a thought.
