I'm in the marked for an android phone. Main use will be the obvious telephone and sms-use, and development of web-based applications towards smartphones. (maybe also native apps, as a java dev it sounds more tempting than developing for iPhone despite its wider use.) But between the htc and x10, I got an ipod, both a dslr and a p&s so neither the sound quality nor the photo quality matters that much. I saw a review of the amoled used in the n1 and the desire. That frankly put me a bit off amoled all in all. Not that I know if the x10 has a better color fidely. Then its a matter of memory, the earliest android phones were left in the dark due to low memory, what about x10 and its 256mb of ram? compared to the double in the desire. Just trying to find the tool that can last a while.
