As I had used old resistive Windows XP tablets in the past, I was not very enthusiast when I bought a HP TouchSmart tm2 tablet convertible notebook for a very specific purpose (Using as GPS with SkyDemon in airplanes). I believed that I would never use this "tool" for anything else than flight planning or inflight gps ... I was wrong !
In fact, there are some minor tweaks in Windows 7 that make it very usable in tablet mode. The checkbox nearby each file in the explorer makes it easy to select multiple files without playing with "ctrl" or "shift", pinch to zoom works almost everywhere, scrolling into the mp3 albums collection with iTunes or WMP works like a charm, the keyboard appears when needed and the capacitive display makes it very responsive.
Even swipe gestures are supported: on the taskbar icons, swipe up on an application and you get a list of the last opened documents, same for IE with the history, swipe left or right to do back/next in IE9 or WMP...
In fact, although I would have liked a dual boot (Windows/Android), I found out that Windows 7 never looks stupid compared to iOS or Android ... as long as we don't talk about power management ;-)
