Is there plans in the near future to build a building taller than the Burj Dubai?

Question

and what is the Burj Dubai used for? Is it an office, hotel, or what?

Answer 1

Like almost all tall buildings, the Burj is mixed use but the top is luxury residential and the lower part is retail / business.  There are plans to build lots of buildings taller, if they get built or even designed is undetermined.  A lot of these projects are 'announced' and then once they start to get press, end up killed.  Look for the Al Burj and the Chicago Spire.  Both are in the same neighborhood in height, if not taller.  Also mile high tower and Murjan tower are listed on the wikipedia entry under competition with other projects.
