Question - especially for those who already have an iPad. Using this to help with my Apple stock forecast. What % of current iPad owners do you think will upgrade to the iPad2 when it comes out? I know there are many (like myself) who wait for the 2nd generation of most products. Those buyers will be significant. I'm curious what the upgrade % will be? My "guestimate" is about 25% will trade-up. Too high or too low?
