I am curious about the 921-- How many are in service at trhis time? 500? 10,000? 50,000?? I ask to determine if this unit is basically stable. If there are indeed 10,000 units out there and we arent hearing of any widespread fatal or near fatal bugs,, can we assume this unit is ready for prime0-time? I dont think the OTA prblm is grounds for not buying the unuit. Then again, if there are only 2,000-3,000 units in service we may still not have a representative sample to base opinions. I want the unit. I will give Dish $300 and my 508 and 6000. (obviously I wont have a 921 until a 922 is released for $599!!!
