Well, technically their SMF info is outdated as well. 2.0 has more features than listed, is free, and is of the same quality as vB or IPB.
myBB still doesn't allow WAP access, still no pruning or archiving, need a plugin for the WYSIWYG (SMF 2.0 doesn't have plug-in, it's built in). I still see no reason to switch to myBB.
yeah, plus it looks like myBB is just a hack of older phpBB code with AJAX thrown in....
