Tomorrow we should know a more accurate release schedule. If the price is anywhere sane I will buy the developer version of that phone.
It's nice to see how development is compared to Android and WP7 I have worked recently. Android was quite fun to work with (porting JB to BeagleBoard) but I have to say that WP7 has been very painful experience - Visual Studio's dark theme is nice though . WP7 is just way too closed and restricted to be any fun work with.
