The only things from sense I'd maybe like to keep in a more "stock rom" would be the camera app and the lockscreen. Everything else I don't really care for. =\
I want the these apps.
I made the same transition as you. At first I hated the dialer and contacts, but they've grown on me.
However that gallery does suck total nuts. You can go in the market and download gallery 3d which is (as far as i can tell) the standard gallery you're used to. I'm using it and it feels right at home.
I absolutely can't wait until we can have CM7.1 on this thing.
Also.. is it just me... or are you totally missing the trackball? I keep trying to adjust the cursor with it when editing text just to get disappointed that it's not there...
I guess it just comes down to what you're use to. I'm use to the 3d gallery because I've had the n1 since launch. I'm trying out quick pic though. Anything is better than the gallery app on the sensation. Sense really has left me a bit underwhelmed. The only things i'd want to keep from sense is the lockscreen and the camera app.
