My WTL 8.0 experience with Windows Mobile development is going just great. The application wizard worked out correctly with only a very minor issue: the WTL include directory is not set up either for C++ compilation nor for resource compilation. As I said, this is a minor issue that you overcome quite easily.
While working for the new Microsoft Bluetooth device inquiry and service discovery (these seem to be the appropriate Bluetooth terms) I found out that Sergey Solozhentsev's WTL Helper tool works like a charm in Windows Mobile projects under VS 2005. All of the message handling functions for the main frame window were generated with this tool and it makes it very easy to write all the UI code - this tool just rocks.
Today I found out about something that does not seem to be documented anywhere: when using the SHMENUBAR resource, never specify a menu resource with a grayed (MF_GRAYED) menu item - the menu will not show up. The WTL code is very straight forward and uses the SHCreateMenuBar API, so this was not where the problem lied. After removing the grayed style from the resource editor the menu magically showed up! So is this a bug on the shell or on the compiler?
