I got the new Mobile Developer Power Toys today and started messing around with them.  The new ActiveSync based remote display is working well, and I think some of the other tools (RAPI_Debug, RAPI_Shell, JShell) might just help me with some of my more bizarre mobile issues.  I'm glad to see Microsoft is releasing more debugging tools because quite frankly, ActiveSync is my sworn enemy at this point.  This is not good when you are primarily doing mobile development.  ActiveSync 4.0 is actually seems quite a bit better than previous versions but there are still quirks.  I should not notice any networking quirks if my device is going through ActiveSync.  Microsoft, are you listening?
