The unwired writes about a more finger friendly version of Windows mobile 6.5 which they spotted here at Xda-developers.com:
While Microsoft put much efforts in making Windows Mobile 6.5 as finger friendly as possible, some things haven't changed so far, at least not on the versions the company showed publically: Tabs in submenus which either still required a stylus or finger nails.
However, Windows Mobile 6.5 Professional's build 21925, which recently appeared on Xda-developers.com, seems to change the design of the tabbed screens for Professional Windows Phones, making them into rotatable pivots as also seen in some Windows Mobile 7 leaks as well in Microsoft's Facebook application.

It's not yet known if this is just another test build from Microsoft or if build 21925 really represents the latest Windows Mobile 6.5 design and development but it's really looking quite promising that Microsoft will finally deliver a finger-friendly GUI with Windows Mobile 6.5
