If you haven't lived with the Touch system for several weeks it's hard to get a good feel for just what is wrong.
To me, it is clear that the Touch system has software problems. It acts as though there is a memory leak with the programming. Depending on the device and the features you use on a regular basis (ie BT Audio), the Touch finally get's over whelmed and starts acting up. ending up in finally rebooting.
Let's hope the software update will have improved error correction and memory management to help deal with all devices. I understand that not all Touch features will work with all devices but Touch should be able to operate without locking up and rebooting.
