IMHO, the most important functional changes Samsung could make in the next software update is to:
ALLOW USERS TO PUNCH IN A CHANNEL NUMBER WHILE ON THE GUIDE, TO MAKE NAVIGATION TO A GROUP OF CHANNELS INFINITELY EASIER. (highest priority)
Add 1080p60 support (currently limited to 1080p30)
Does anyone else have a wish list?
One other thought...
On many of the automobile forums, the car companies monitor them, and have customer service reps actively informed, getting real-time information on problems from their highest-value users, and actively working to solve problems. On the Chrysler minivan forums, it works extremely well.
Could we invite Samsung reps to his site, and do the same?
