They may be referring to the thing others have mentioned that when syncing the iPad, they are getting an alert that so many apps will be removed, if they proceed.

When you plug it in you can right click on it and click "transfer Purchases" it should save all of the current apps on the Ipad on your computer. so you can put all your apps on both computers.
I had my brother in law provide me his password and used it from my iTunes to authorize and transfer purchases. However, the next sync removed the apps but did create a new fielder within iTunes where the apps were stored. I them dragged them to my iPad icon and boom! There they were back on my iPad!,
Thanks to everyone for all your help and advice.
