For obvious security reasons modern era presidents avoid e-mails. Clinton sent just two e-mails as president while Dubya didn't use e-mail at all during his time at the White House.

Through three separate interchangeable modules, it works with Wi-Fi, GSM, or CDMA networks, and is dust-proof, waterproof, and rugged enough to survive repeated 4-foot drops onto concrete. Physically, it's a chunkier second cousin to the Palm Treo 750, though with an additional LCD display below the keyboard.
The price is $3,350 with a two-year warranty...
