Here is my first impression of pure stock Android 2.3.7 Gingerbread (Oxygen ROM is pure stock).
What i liked:
-rounded statusbar/notification bar
-NO CANDY LAND THEMED FEELING
-vertical app drawer
-retro android feeling off pressing >add>widget or what ever else
What i did not like:
-Oxygen ROM gingerebread keyboard is not like the stock though, its rigid and small, hard to type, but atleast its not twice as small as froyo keyboard like ICS, but only about 1.5 times smaller, but thats ok, "GO keyboard" (app on market) has a great gingerbread theme.
Other than that, Gingerbread is amazing, its just a darker froyo and i love it, it is my favorite UI.
Is it worth getting it, heck yes! You wont regret it, but when CyanogenMod fixes my problem with the screen, im gona try it out and make a review about it too.
