Update came up today for me, and installed without a hitch.
I haven't had enough time yet to thoroughly test all functions, but WiFi appears to be working fine, and haven't noticed any graphical issues in YouTube or the Recent Apps list as of yet.
However, I've noticed a few pauses/delays in processing which appear to be intermittent (i.e. opening/closing apps, browsing the Market) -- has anyone else seen this? I'll need to monitor things, as I also feel that my battery has drained faster than normal today. Could be related to the delays, if something is for some reason bogging down the CPU. I'll update on this in a few days or so.
