During the week in September that I was attending the Microsoft Build conference and learning all about Windows 8, only one topic made me gloomy: This was the Windows 8 implemention of the Manipulation events. These events provide a high-level application programming interface to touch input, so obviously they are very important.
At first glance, these Windows 8 Manipulation events were somewhat enhanced versions of the Manipulation events in Windows Phone 7 (which themselves were stripped-down versions of the Manipulation events in the Windows Presentation Foundation) but these enhancements did not fix a nasty flaw in the Windows Phone implementation, and that didn't make me happy at all.
