Note that if you go to about:plugins, Flash still reports 10.1, you have to click Details at the top right to see the 10.2 version file, not sure why this is. The big question is how does Flash perform? I was able to play a 720p Youtube video with decent performance. I've yet to try other flash content like Hulu and
If you get updated let us know how Flash does for you and any other differences you notice in the comments!
Update: No go on Netflix, they still list Chrome OS as incompatible. There also seems to be a sound bug. It worked fine until I tried to turn the volume up at which point the onscreen showed the volume as muted. No pressing of the volume up down or mute keys would undo the mute :-(
2nd Update: Ouch! This one might get ugly. I logged out to see if the sound might return with a new session. Instead of the login screen I was greeted with the Out of box "Let's get started" screen! Looks like some issues with detecting that I've already run through the setup. Luckily once I ran through that and logged in, my user settings were untouched. Well, when you live on the bleeding edge, sometimes you've got the edge and sometimes you just stand there bleeding... Gonna try a reboot now...
3rd Update: Volume control buttons are definitely borked. As a workaround, open a shell and run "alsamixer" to use a non-GUI volume control, it works and can unmute the sound or adjust volume when needed.
4th Update: I toggled the Dev switch under the battery this morning in order to wipe the stateful partition (wipe to factory defaults). That appears to have gotten rid of the volume issue and the strange return to OOBE on logout or reboot issue. 720p videos are jerky but I'd characterize it by saying that flash support is definitely improving with plenty of room for more improvement.
5th Update: It seems that although Flash 10.2 is included, 10.1 is also still included and is the default. You can disable 10.1 by going to about:plugins, clicking Details to the right and clicking Disable next to 10.1. You can verify what version of flash your Cr-48 is using here.
