I am not sure about video quality since all of my stuff is converted to mp4. Those do look good.
No andoid hacking since the bootloader is locked.
The Android Player is useful, but you will need to find apops converted for the player or convert them yourself. The player is fairly stable, but it can hang if you launch a lot of android apps without backing out of the running ones first.
It's a good device for videos, music, internet, and limited android apps. Certainly worth $120. The strength is the storage and its fast enough. hopefully when BB dies, they let us unlock the boot loader.
