That is really not a considered attitude. Tons of users find them not only usable but necessary. Internal mics aren't the reason for the lack of digital input. It is common for people to only consider their own use, specially in specific related forums.
I have no idea what a 'considered attitude' is... And I don't quite understand your link between digital inputs and internal mics...
I really cannot imagine why internal mics would ever be necessary apart from for people conducting interviews and wanting unfettered portability or in situations where external mics have failed/been forgotten.
For me, the internal configurations on these budget recorders really seem to be too fraught with compromises to be considered a decent option: (presumably) cheap mics, which are generally omnis, minimally spaced and in direct contact with the recorder and thus likely to be subject to handling noise. Plus the fact that your placement options are highly likely to be limited by the fact that mics and recorder are effectively one unit.
I think a big difficulty is that these 24 bit recorders seem to make people think that they are a one-stop solution for high quality recording. Which is not to say that it's impossible to make a listenable recording with internals, just that I suspect that a cheaper recorder plus relatively cheap external mics + a bit of thought could easily give a much better recording.
