OK, I get those points, but just wanted to point out that there are some of us for whom small isn't necessarily better. In my case I'm "on site" (at my buddy's house) recording stereo piano (from one to three separate parts), drums (four tracks: kick, snare, overhead left and right), vocals (one to three separate parts), multiple guitar tracks, and the odd synthesizer tossed in. Internal microphones won't get the job done in terms of quality or number of inputs, and the sixteen tracks available on the R16 provides a comfortable fit. The R24 may at some point be kind of nice for the extra tracks, but patterns, drum machines, etc. hold no interest for me. I was happy to shell out for the R16 (found a deal for $345 plus free shipping for a new unit) and have no regrets.
After those remote recording session when I get home, I'm not in a situation where I find myself trying to squeeze in a few minutes here or there to work on songs. My kids are getting older now and I have plenty of time to lose myself in this stuff. I have my environment set up with a swivel chair so I can easily reach the circle that's comprised of my computer, my Yamaha keyboard, and guitar stands that have electric, acoustic, and bass guitars within easy reach.
As far as selling more units because they're cheaper, it's safe to say that McDonald's sells more cheeseburgers than Microsoft sells copies of Windows, but they both seem to be able to make a buck.
Anyway, I just wanted to express the opposing viewpoint because some of us are pleased that Zoom is focusing on more than just hand-held units. I don't refute the usefulness of those units and acknowledge that they're the best solution for some people. But some of us have different needs and Zoom is smart enough to recognize that.
