Ha ha yes, every laserist should have a camera with a CCD like a teabag. It's certainly seen some battle in its time...
I guess that's down to personal preference. I prefer it because buttons give a more definite feel than a touchscreen, also the performer buttons light up so you can see which cues are active. I tend to design my workspaces with separate frames, effects, key effects and colour cycles and then control them independently, so this board shows me exactly which ones are running... My touchscreen didn't lay flat like this does and I usually stand when I'm doing a show, so this feels more natural to use...
I have some shows this year with lasers in two arena's, so the old gear will be used to control arena two at these gigs...
The MIDI controller adds extra functions that the performer doesn't have... I have four faders configured to fade each track in and out (I assign different projectors and zones to different tracks). Then I have faders configured to control effect, key effect and colour cycle speeds independently, knobs control transition time, Beam and TTL chasers... So really adding the MIDI means I very rarely touch the laptop...
Most of my gigs have pretty fast music like breakbeat, drum & bass and so on, so this setup allows me to make very fast changes to the show in time with the music... When dubstep happens I get chance to rest and slow things down... Only downside at that point is that I'm forced to listen to dubstep
