Don't care what the so called 'professionals' think,'adopted' it may be but it's a planet.

New stuff out today:

This is awesome - make sure you click the thumbnail for the BIG image!:
http://pluto.jhuapl.edu/Multimedia/S...2&image_id=319

And I think this is an even higher res version (full res mosaic?) of that image above (warning: very big file - 67MB):

I wonder if these images were available a decade ago, if Pluto might not have had a stay of execution for a few years.

If we had pictures like this of Eris would we call it a planet too? We have similar images of Ceres, though it's not nearly as visually spectacular, should we call it a planet?

It doesn't really matter whether science classifies Pluto as a planet, dwarf planet, TNO, KBO, whatever, but surely whatever label(s) science gives to Pluto needs to also be given to the other similar bodies. The way I see it having an exception to the rule doesn't really work well in science.
Having said that, of course scientists often need to classify things in a way that popular culture won't accept or adhere to so I guess we, as non scientists, can call it whatever we want.
Personally I'd prefer it if Pluto was still classified as a planet and our Solar system had 14 planets but nobody listens to me, and either way Pluto is still Pluto

That's not what I said.

Eventually Pluto would still have been demoted. Having clear details of what are clearly planet style features would have strengthened the argument to keep Pluto a planet, delaying the inevitable decision.

In the interest if twisting tails (probably more Brent's than yours)... which "planet-style features" should have strengthened those arguments? Which of them do not occur on moons like Titan, Enceladus, Europa or Io? Titan's river channels, hills, lakes, atmosphere and clouds are especially planet-like!

There's an amazing range of really cool stuff that goes on beyond the frost line in the Solar System, and it's been a joy to see some of the imagery coming from probes like Cassini and New Horizons, what a great time to be watching

You've pretty much nailed it with those features. If, say Io wasn't a moon, but was orbiting on its own between Jupiter and Saturn, the case to call it a planet would be very strong.
It would be visible to the unaided eye, spherical, have clearly active geology, and not asteroidal in nature.
The test that was created (and that pluto fails) is that it has not cleared its orbit of other similar sized objects.
Move Pluto's orbit closer to the sun, and assuming it's surface features don't evaporate away leaving just rock, I'd say you've got a bone fide planet.
