I would probably use the Magnus as a living room pc using the TV as a screen or getting a small projector and using that. Then get a wireless keyboard and mouse and you're golden.
Hmmm.... Might have to take a look at the Z2. I really like the glove option coz i use gloves when i work and using my Galaxy S3 is a pain with gloves. I recommend taking a look at the dbrand custom skins. Man that bamboo skin is gold.
