If I remember correctly, Wilt said that the display is way to bright when enabled. Enough so that no one would want to turn it on. I have a Moto DCT5100 from Comcast and the display is about the same dimension as the Voom box, however I think they have the luminosity turned down, cause it's not overwhelming in low-lighting situations.
I would like the channel number. The numbers on the screen are very hard to see from saccross the room. I remember my old Primestar STB. Had the channel numbers on the front. Made it nice to see at a glance where you were.
I like being able to show the time on-screen with the touch of a button on the remote. It can instantly be turned back off the same way. I only see it when I want to rather than having a numeric display on all the time on the receiver. The menu and PG displays aren't pretty on the VOOM box, but the text is big and easy to see at a quick glance. As for the channel number, I always know what channel I'm watching anyway.
I'm hoping the programmers don't waste their time on something like a clock or channel display on the receiver. Let them concentrate on more valuable operational features. Heaven knows we could use more of them!
