Longhorn is the codename for the next full release from Microsoft. It's supposedly a completely redesigned 64bit platform, including rebuilt security, functionality, file-structure, and services controllers (to name a few). It's been pushed back about 4 times now, making it about 2 years overdue. The pushbacks are good, though, since MS has decided to fully address their security and services issues this time around. What comes out at the end is supposed to be a completely new version of Windows, which should solve many of the fundamental Windows security problems of the past.
Of course, we'll have to wait and see. There's already talk about pushing it back yet again for another season.
The beta version available is basically MS's attempt to get a 64bit platform out to the public. It's buggy, bulky, messy, and in its current state has been completely trashed and will not reflect the true release.
