Some suggestions on the survey.
You left out Pleo RBs. Was that intentional?
There have been very few OS versions
shipped with the same model of pleo (3 for Ugobe -- 1.0, 1.0.2, and 1.1; 1 for Innvo -- 2.0; 1 for Merlin -- 2.0; and 2 for RB -- 1.0 and 1.1) and most people have no way of telling the versions apart short of using one of the software tools. It's great info to know, but I would probably say to drop that question as you probably won't get good data.
Likewise most people who buy pleos used (as well as most of the people selling them) have no idea if they really have an original Ugobe or an Innvo Labs or Merlin edition. They usually come here to the forums to help figure out what type of pleo they have.
On the Pleo coloring, "2006" is wrong. The original pleo didn't come out until 2007. All Ugobes have the same color (dark green). The yellow tail color is the "2009" Innvo Labs model. So, if you have the "2009" coloring, it's either an Innvo Labs or Merlin edition.
As you review the data from your survey, you'll need to cross check these questions to make sure they match up correctly. If someone reports they have a Ugobe pleo with the "2009" color running the 1.0 OS, you can be sure they got it wrong. They most likely have an Innvo pleo that's been downgraded to 1.0. Likewise a Ugobe pleo with the original color running the 2.0 OS was upgraded and that's NOT the original OS it was shipped with.
For RBs I think you should ask that the skin color and eye color are.
Also, if we can get people to register their pleo here on the forums, I can get you all that data. Click on the "Pleos" tab at the top of the page or go here:

One of the things I asked for many years ago was for people to run Dino-mite and give me the report from the tool. This is a much better (and more accurate) source of data.
