This custom ROM is simply my favourite of all the availible ROMs out there.
-It is very basic. Means it doesn't use a lot of internal memory space.
-The energy usage is VERY low. You can use your phone permanantly for almost a full day.
-It runs very smooth and stable.
-The new google OS for Android Phones is included: Gingerbread 2.3.3!
-Gingerbread almost doubles the overall gaming capacity of your android device.
I've installed this ROM myself on my HTC desire and haven't had problems since.
