I've had the Q for over a week now and it's great! PC Mag and CNET gave it a great review, but you'll see lots of negative user reviews from people who arne't familiar with the Windows Mobile platform. This is a smartphone version versus PPC version, which I personally like better. It works better as a phone (like candyflip said), which is why I hated my old PPC (Cingular 8125).
Windows Mobile takes some getting used to, but once you've figured out all the shortcuts, the benefits are awesome. I use it to access my slingbox (home tv), listen to howard stern, and play movies. As a phone, the quality is good and loud. The fact that you can fit all this in a slim phone is awesome. The Q will be huge, and watch for tons of accesories and software to roll out specifically for it.
