Would-be testers of the tablet-style computer, due to be released Apr. 3, must promise to keep it isolated in a room with blacked-out windows, according to four people familiar with the more than 10-page pact that bars partners from disclosing information about the iPad.
To ensure that it can't be removed, the iPad must also remain tethered to a fixed object, said the people, who asked not to be named because their plans for the iPad have not been made public. Apple (
AAPL) won't send out an iPad until potential partners send photographic evidence that they've complied.
