Actually, since I'm still up here are some early findings (and up to the minute stuff is always in my Twitter feed):
- In terms of looks the ROM is a bit frankenstein at the moment with a mixture of TW/GB/ICS elements throughout the UI
- Performance in general UI navigation is a big step up from GB ROMs, even custom ROMS, and that is despite this one limiting the CPU clock speed to 1.2Ghz/core (because the i9220 version runs at that)
- Graphics performance upped a lot - 44fps in Nenamark 2 which is basically the same as the Transformer Prime on ICS (in other words, wow)
- Realised how much I missed some aspects of ICS since I went back to the Note on GB as my daily driver a while back, the task switcher is brilliant, as is dismissing individual notifications, the browser is just superb (and the Chrome for Android beta is also incredible, although lacking some nice features of the ICS default browser at the moment like saving web pages for offline reading and inverted rendering in the browser)
- Everything working fine, I had a couple of FC's when accessing 'activities' in ADW Launcher but I think that's because the Settings structure is changed in ICS and so the GB shortcuts point to the wrong place (ie not a stability problem on the ROMs end). I will say it again: this is already easily good enough to be your daily driver
- Inbuilt Google Apps are of course lovely in their ICS incarnations
- Face Unlock present and working in all it's novelty-not-security glory
- Voodoo Louder doesn't work on this since the phone identifies itself to the app as an i9220 rather than N7000 (apparently an N7000 native ICS ROM is leaking tomorrow)
- Too early to be definite but wakelock delay seems drastically reduced, now just fine
- Apps with stuff specifically for ICS work with this build, for example notification player controls for PowerAMP are present (YES!)
