Silly Survey Sunday: Have you upgraded to Tiger?

Now that the dust settled, how many of you have actually made the jump to Mac OS X 10.4 Tiger?

If you haven't upgraded yet, but you want to – what's the biggest thing that's holding you back?

Is it the handful of critical applications that still don't function properly (or at all) under the new OS?  Is it corporate policy?  Is it the expense? Are you still recovering from the Panther upgrade?

Or are you just not that into Tiger?
