I've owned an X50v for quite a while. For video (using TCPMP -- now Coreplayer) it's amazing with its accellerated Intel chip. Yes, better then the N8xx. But other then that ,I'll be glad to get rid of it once my eBay auction ends. Battery life is really poor, especially if Wifi is on (god forbid) or an app is running the CPU much. It makes me laugh thinking about having my n800 online and available for days.

Also in the world of Windows Mobile you also end up paying for apps more often then not. There are decent free apps, but they are the exception. I still use Windows Mobile via my phone (Moto Q) but other then that, I'm glad to be done.
