Senator Joe Biden would become the President-Elect if Obama were to become unable to server as President (eg. death) beginning December 15, 2008. Should President-Elect Obama be unable to server as President prior to December 15, 2008, the day the Electoral College votes, several scenarios might happen. Some states are required by law to vote for their states voted candidate (ie. the President-Elect that can't server). Other states can't select whomever they choose. To answer your question, if it is after the Electoral College vote (12/15/2008), Senator Biden, if it is prior the Electoral College, it is unknown (Biden, Clinton, McCain, Palin, or someone else). This has never happened in US history.

The Vice President of America.
Barack Obama IS president of the US and is doing a very great job.
The vice president takes office if the president dies.
If both of them die, the speaker of the house becomes the president.
The vice president is promptly sworn in as President if the President dies or resigns. This unfortunate event has already happened nine times in US history.
Yes! The Vice President, the the Speaker of the House. This is the current line of succession: http://www.patriotstoolbox.org/america/presidentiallineofsuccession.htm
If any US President were to die during their term of office, then the US Vice President would be sworn in as President.
If Joe Biden dies, Obama will remain President. If Joe Biden dies while Obama is President a new Vice President will have to be chosen by Obama.If your question was based on who would be President assuming both President Obama and Biden both died, that would be the Speaker of the Hosue, Nancy Pelosi.
The Speaker of the House, currently Nancy Pelosi http://www.patriotstoolbox.org/america/presidentiallineofsuccession.htm
