All Windows Phones are bad
All Windows Mobile phones are bad. They all need a stylus pen, even the HD2, as most of the apps aren't finger friendly. The OS is designed for the stylus-driven Pocket PC, not a telephone. This interface belongs in the 1990s.
If you're reviewing the HTC HD2, you should mention that the camera defect still has not been fixed, which puts a pink circle on every photograph. The phone is pretty buggy, needing restarts every day.
And there's no point buying a 'smartphone' if you don't have any applications. The developers have fled Windows Mobile, and have gone to Android and iPhone. If you look at Microsoft's app store, there are very few new applications coming. It's mobile app store is a ghost town.
There was a survey in InformationWeek (a few days ago) that said that Windows Mobile is now losing the business market, falling to just 24% in the enterprise. Blackberry and iPhone are now used more in business than Windows Mobile.
So don't recommend any of these phones. The Windows Mobile platform will be axed in the next year. But don't worry, the HTC Passion will be out in January, running Android. Also Sony-Ericsson has made its final Windows Mobile phone, the X2, and its next phone, the X10 will be Android.
