@RoyTellect: I'm personally pretty happy with my Dell Venue Pro, it works great as a phone, music player and "keep in touch with people" device. The only "missing feature" that personally affects me significantly is that there's a severe lack of music-related apps compared to the iPhone/iPod touch, which is partly due to the lack of an exposed native API to enable low-latency interaction. But I also have an iPod touch v4 so it doesn't bother me much...
However, I've also heard that outside the US (where I live) some of the key services, like Zune, associated with the phone aren't available yet, so some of the advantages (the Zune Pass service is pretty great) don't apply. So if you're in Russia it might be better to look elsewhere (or wait a year, since the Nokia deal will probably improve things in this respect).
