There are quite a few differences that might be a problem with GET. In get the the values arer passed with the URL, which means that the user will be able to see what is passed. Also it means that you can endlessly refresh the same page with the same parameters, which would be a problem if the page updated a database. Finally in the get method there is a limit on the amount of data that can be passed. This limit is browser dependent.
