HTC's Sense UI runs on top of Windows Mobile 6.5 on the HD2, providing a better UI and convenient shortcuts to Windows Mobile apps. It's finger-friendly and hides most of WM 6.5's software and interface flaws. Sense UI is a slick and mostly well thought-out interface, but it has a few shortcomings of its own. On the home tab, the first screen you see when you power up the phone, the quick links to your favorite apps are limited to nine; the calendar contains only one entry; and there's no task list. Co0kie's Home Tab (CHT) fills these voids.
