1). It is basically fairly easy to navigate around (A whole lot better than the DM-24 was laid out). As far as the "02R" style is concerned, well, it's present here too. But fortunately the menus are logically laid out, as well as the physical controls for navigating through them. Also on the plus side is the fact that EQ and compressor settings can be made entirely from the front panel LED ring encoders. Which is a nice feature (especially in the low light situations, and looks cool as hell).
2). As far as DAW resolution goes, I have nothing to bitch about yet. I basically use it to write pan and volume changes (which usually get fine-tuned anyways). I love the layout of the Machine Control/Transport section. I'm sure I'll find something to bitch about here eventually, but I'm still infatuated a bit too (Hell my last controller transmitted cc64 (center) at about the 2 o'clock position, anything was step up over that).
3). I've never been a fan of Tascam Pre's (analog or digital), and have always liked the Focusrite Platinums. Simple as that I guess really. I guess it is because they are very sterile sounding. I'm not a fan of the ultra-transparent (But hey all the power to those who feel they need to spend $5000 on a pre, to sound good

).
It is worth noting that I have not utulized the Firewire interface yet as I'm still waiting for an update to
the DM-3200 to implemement it (However I've seen the same interface work with the DM-24, so I'm not to worried about that), so in the meantime I'm using my M-Audio Delta's to the max (Obviously I'll be able to really maximize its use when I can interface 32 channels to the DM-3200 from my PC, send 16 back to the PC, and still mix all my MIDI and additional tracks within the PC via the DM-3200).
My only real gripe so far is that the touch-sensitive faders seem a little overly sensitive, and while working on at least 2 seperate tracks I realized that I had accidentally selected another track (Via bumping a fader while working with the encoders), and had to subsequently undo the changes and reselect the track that I wanted to edit. So now I have disabled the touch-sensitivity (after all there is a Select button for each fader anyways).
