So, the ability to download photos from your DSLR, and upload to flickr or similar, with only your phone, would be of no interest (and if you can do that, controlling operation of your DSLR for time-lapse photos etc. should also be possible)? And, if your DSLR (like mine) supports HD video (with better lenses than phones with this capability), you would have no interest in being able to play that video back on HDTVs, at HD res, from your phone (in case you are visiting friends without your DSLR or laptop)?

Both of these features would be of interest to me, but hopefully host mode on N900 will get us the first, and for me, the 2nd isn't enough to prevent me from waiting for a Maemo- or Meego-based device with HDMI out, but it would still be of interest.
