Lately have been using my Asus T91 MT a bit too frequently, primary to write documents and occasionally to browse the web. Though I constantly use the tablet, I hardly thought of two things: faster way to login my machine and better touch friendly window title bar and scroll bars. The rest of the elements in Windows 7 appear to be quite touch friendly to me, but not the above mentioned ones.
During the previous iteration of Windows, Microsoft had released a set of tools called Origami. These tools were specifically meant for touch based UMPC tablet PCs. Two of the tools offered by Microsoft Origami: picture password and touch settings have made a pleasant difference to how I use my tablet PC. You can download Microsoft Origami from here. But note that you may not be able to use other Origami tools on Windows 7 except the ones that I have mentioned. With Asus releasing the "most powerful TabletPC on earth" , probably its time to revive origami for Windows7.
