Is Obama's handheld a BlackBerry or something else?

you can't read it? hrm. well, the article speculates about what it is he might be using:

"The security analysts speculated that Obama will use the Sectera Edge, designed by General Dynamics Corp. and L-3 Communications, because it meets the government's highest security requirements. It runs on Windows CE software, not the BlackBerry operating system, and it presumably would not rely on an e-mail pathway through a network operations center outside of the U.S., as the BlackBerry does, with NOCs in Canada and Europe."
