Go over to the ROM thread in the GN section and check it out. So far people (only a couple at this point) are reporting that it is great. Only bug anyone's reported is having to use the Set CPU app to change the cpu settings. According to the dev, there's going to be an update coming in a day or so. I might wait for that to flash.
I installed 1.0.1 yesterday and it is really fantastic. Haven't had much time to play with it but it is very smooth with tons of customization. This is my first ICS ROM so I don't know how it compares to the others out there but I'm very happy. I just downloaded 1.1.0 and will flash with the new gapps. Codenamedroid has put the new version out at RootzWiki, hopefully it will arrive in DF soon. Here's the link: [ROM][AOSP][4.0.3] Codename Android 1.1.0 [Fully Open Source](01/12/12) - RootzWiki
