They have alot going in their favour
They have experience making reliable hardware - so a RROD situation is unlikely
They have experience making exremely easy to use software - good user interface
They have a loyal fanbase
They also have alot of things they woud need to work on
In the case of their C's, they only focus on the upmarket, high end devices. They can't do this with consoles
They have no 1st party studios (yet)
It'd hopefully do well
