HTC HD2 is the first Windows Mobile-based device to do away with a stylus for navigation and control through the functionality built into the apps by HTC. There is still no native support for multi-touch in the OS itself. Infact it is HTC Sense which is super imposed over Windows Mobi
le 6.5 to make the device look modern(ish) and multi-touch capable. Furthermore, we all know that iPhone is definitely a trendsetter in the world of smart phones when it comes to its multi-touch functionality, App Store etc. It was all very well thought and put together by geniuses’ at Apple almost two years back with the original iPhone. So it will be fair to say that HTC and many others are playing a catch-up game on Apple’s iPhone with certain improvements, rather than introducing something really new of their own.
