I think the time line is interesting.2010. First Dragon test launched on first F9 2012 Cargo deliveries start to be berthed at ISS2019 First docking of crew rated Dragon to ISS7 years from first arrival of a Dragon at ISS.I'd love to know where most of that time went. Specifically who raised the lions share of the complaints, issues and questions. My guess is either ASAP or the Russians, for different reasons. ASAP couldn't believe an aerospace company that didn't exist during Mercury, Gemini, Apollo or Shuttle could be any good and the Russians because they know their era of charge-whatever-they-like is coming to an end. TBH I doubted if NASA would give SX the first go at launching to the ISS, but they did. Congratulations to all at SX for their perseverance.

FYI on the Amazon comment, I went to Blue Origin in Kent to see their facility and they told me that whenever SpaceX had a big launch or rendezvous the BO crew would all get together in front of a big screen and watch. They would cheer enthusiastically on SpaceX’s success. I thought that was great.

A plushie of some sort? Didn't Elon want him getting 'lonely up in space' or something?Think of it the same as the plush toys the Russians bring along on the Soyuz flights, a zero G indicator.So where does one go online to buy one of these for the grandchildren?Can't find anything quite like it on Amazon. Probably can't find it on Amazon since it wasn't a Blue Origin capsule.

They were available - search on 'GiggleBeaver Celestial Buddies - Earth Cuddly Toy' in Amazon, but out of stock, there was a run on them a couple of days before the launch.

Will they in future be using the Dragon 2 when it’s docked to the ISS as part of the living space of the station being as unlike Soyuz it is quite roomy?

I believe that this was mentioned in one of the NSF articles covering this mission.
