90% running 4v>IPA or Nbox>m10 in my pocket. Thinking of a backup deck, kicking myself in the arse for not grabbing another m10. Not too thrilled with the Roland R05 line in specs, and really not too jazzed up by tascam DR05 or 07. Is there something else out there with M10 dimensions? I know the D100 is bigger due to mics, but If it is a hearable upgrade, I'd be inclined to go that way, since there doesn't seem to be a 4 inch alternative to m10 anyway. Thanks for your opinions!
