As noted yesterday, Barack Obama will be the first US President to have his weekly address shoved on You Tube. Indeed, he'll be the first President to have his regular broadcast available in pictures rather than just in audio via network radio, as it has been before.
Votemaster notes that Obama will also be the first President to have a computer on his desk. He has asked for a notebook computer in the Oval Office.
Sadly, he'll have to eschew his beloved Blackberry due to some footling Presidential Records Act or somesuch.
