What about the pressed pennies? What did I miss?
A lot of the pressed penny machines have been replaced with machines that cost $1 per penny and only use bills or credit cards, no coins (they supply the penny - or, in some cases, just a penny-sized copper disk that was never money to begin with). Some of them also do the pressing part automatically, although some of the new ones still have a hand-crank.
As for Galaxy's Edge, I do think it's visually excellent. It does feel like you have entered another world, and the two times I have visited, I found it strange to remind myself that the Muppets and Toy Story and the rest of DHS were so nearby - it really did feel like I had been transported to somewhere completely different.
The interactive elements on the Datapad game were somewhat interesting - I played through several missions and scanned a lot of crates, where I "found" some fun virtual items that I recognized from the movies, which was fun. Unfortunately, the Datapad was also pretty un-intuitive, and I sometimes struggled with how to progress to the next step of the mission (hint: you have to click the ? button once you have reached the mission location in order to confirm that you're there). I spent about 20-30 minutes playing with the Datapad before I ran out of missions that I was interested in. I do wish the game had more real-world elements, like the Agent P missions in Epcot, instead of only giving in-game responses.
I did have some frustration with the pacing of the game in the line for the Millenium Falcon, as the line moved faster than the game in some points. I'm assuming the timing will line up better once FP is operational, but for the time being, it was frustrating for the game to continue referencing areas that I had already passed, sometimes without giving the option to skip ahead. (Interestingly, this sort of matched my feelings about The Last Jedi - I enjoyed all the individual parts, but thought the overall pacing was off and it was hard to tell what the ultimate goal for the plot was, so you had no idea how much time was left or what to look forward to.

I actually really liked the shops. They had some really cool items for sale - I thought the toy shop was suuuuper cute, I was amused by the Batuu-themed water spray bottle fans, and the authentic-looking Jedi robes and tunics were really tempting to me as a cosplayer. The only problem for me was that the stalls were so small that I felt like I couldn't just stand and look around as long as I would have liked, because I felt like I was blocking other guests. And I was on my own - I'm not sure how you could even fit in there with multiple people and try to show each other different items, etc. Even Dok Ondar's was smaller than I expected, though maybe I had just overhyped it in my own mind - there were some really cool items on display there, but it was still basically set up for one loop around and then exiting, rather than spending any time exploring.
I did have good interactions with all the CMs in the land. On my first visit, I brought my shoulder banshee from Pandora and got a lot of great reactions. On my second, I was wearing a rebel alliance T-shirt and was "caught" by Kylo Ren and some stormtroopers while I was paying attention to the Datapad game, so I got some grief from Kylo to "be careful where you place your loyalties", etc., which was great. And I enjoyed seeing Vi Moradi running around pursued by the stormtroopers a couple times on both visits.
I think once they open RotR, if they just also add a stage show of some kind with a couple performances and the march of the stormtroopers or some other sort of mini-parade, and fix a couple little issues with the Datapad game, it could be a really excellent area to spend a good chunk of time. Opening without RotR was definitely a mistake, though, at least at WDW. They created a situation where a lot of people wanted to avoid this timeframe because they were worried about opening crowds and a lot of other people wanted to delay their trip until the second ride opened, so instead of drawing people rushing in, they created two huge reasons to avoid the land for a couple months, on top of all the construction and other issues in the other parks. Just not good timing, and it's showing.
