FWIW, I have this ROM running on a Samsung Fascinate at home. Runs like a champ!
I love it on my GN too. I think will be my daily driver from now on, but there are a few things the CNA has (in ICS) that I would like to see. Not sure if these things might become part of CM10 or if I should start looking at other options.
First is I would like to get Fast Charge mode. Is something I might expect from CM or should I start looking at kernels? I would prefer to just use the kernel the ROM ships with, but I might take the plunge if Fast Charge isn't something CM will do.
Secondly, I want to control how many home screens I have. I would rather have this baked into the ROM, if it's not likely to show up in CM then I'll start looking at launcher apps.
Thanks.
Fast charge is an option on France (and I think Trinity, too) and both have color mods, so you should be good with either one.
As for the home screens, just DL Apex or Nova. I think they are both updated for JB now.
