Wow, thanks Jim (and all Devs), I intend to upgrade, just need to find 
the time and plan the steps....(I plan to create / implement a new 
backend which complicates things) Yet another reason to do it sooner 
than later - and to not yet throw out the "slower" ION R3610's! Thanks 
again for the heads up and the input!
