I've not seen a digital projection yet - I think the nearest cinema to me with the equipment is Manchester, and the new trilogy wasn't worth the trip.
However, I would have thought that you'd still have some flicker there - it's still being scanned serially.
Personally, I prefer the more immediate 'live' look of interlaced video. I've worked with analogue video for about 12 years now, and digital for the last three. I'm currently working on digital restoration of old analogue videotapes, which is an interesting challenge!
