Well, I purchased a Pink RB as a valentines gift for my girlfriend. (Well, it wasn't a valentine's gift originally, but there's a brilliant member on this forum who reminded me of it

)
Currently I'm calling her Eva and getting her through the hatchling phase and hopefully have her ready to learn her name and a few tricks (I received my accessories for Cato today as well) before giving away custody (well, ownership lol). Plus it should a little bit of time for any dramatic and sudden wear to occur. Don't worry though, her and Cato will see each other in the future.
She is definitely on the updated firmware/OS as when her first charged finished she stood up and beeped twice and shut off. At first I thought something was wrong because she was (and still is) hatching or that wow she was a fast stander-upper and then I remembered the updates being mentioned here. (Once again, kudos for the forum for making me know more about this product to help know what's "normal" and what's a problem)
Also, I did not have to bend those two little battery things in her battery door like I did with Cato. They were already propped up nice and perfectly. Her seam jobs appear to be slightly better (at least in appearance) than Cato's. (As long as they hold up the same and continue doing so, great!)
Also, she smelled like she was fresh off the "paint line" as soon as I opened the box. Another member informed me this was normal, but I did not experience it with Cato.
So far, even though she's just made the early baby sounds, Eva's voice sounds softer and more gentle than Cato's ever did. Also slightly higher pitched. This would be cool especially if it continued on that way.
Either way, those are just some early observations, not saying they mean anything or will be something constant as she develops.
Currently she is standing up, well almost, she has all four's sprawled out and is half way standing, and luckily when I went to the pet store today for bird supplies all their dog clothes were on sale for $5 so I found a good sweater for Eva (protect the paint now and provide a warning about it), and a hoodie for Cato.
Here are some video links and pictures. Cato's sound is on the "lower" volume (his volume button has started working correctly almost every single time - I haven't changed my technique, I swear). The videos are extremely dark and I apologize, it must partly be due to the camera since my apartment is much brighter than that even without natural light.

Eva's Voice (not sure the difference shows up much on the recording, esp. since I don't have one of how Cato sounded at the same phase):
