I've been playing with mine for the last couple of hours... I've already rooted the thing and installed Titanium.
Here's a few points:
-I hate Blur. When I import my Google contacts, it also includes "Other contacts". So my contact list has over 400 in it, including people I've communicated with only once, 4-5 years ago. There's no way to change this- it ignores Google contact subgroups. Really annoying, but I can live.
-EA games from Marketplace don't work. The Sims3 and NFS demos were quickly uninstalled (since it wanted me to buy these- I already own them). I installed the full versions from the market, but neither will start because I get an "unrecognized device" error. Needless to say, EA sucks.
-Screen isn't bad. Pentile doesn't bother me much (my two previous phones were both AMOLED btw).
-Very easy to root, and enable sideloading and tethering.
-This thing is a beast. While the EA games won't load, the other 3D games I've tried were smooth as butter, despite the resolution increase.
-The screen even at 1/4 brightness is brighter than my AMOLED Nexus One.
-Mine came with a new SIM card. Unfortunately, I didn't know how to enable it, so I put my old SIM and it works on HSPA+ fine.
-I need to figure out how to enable HUSPA...
