The screen is beautiful! 480 x 640 may not seem like much, but when you cram it onto a 3.7 inch screen, the pixels almost disappear. My last PocketPC was an Axim X5 and the difference in the screens is night and day.
Wi-fi is pretty great too. This is the biggest difference I see between the X50v and my last handheld. The fact that I can be connected at the kitchen table, out in the yard, wherever, makes a PocketPC so much more usable. With my old X5 I had lots of Avantgo channels setup, but the real-time browsing is just so much cooler. The range rivals that of our Laptop with a Netgear 802.11b card.
