seriously, for it to be on a tablet and be successful, FF Os needs maybe 5 things to be successful:
*easy to connect to wireless
*fast surfing of websites
*long battery life
*easy to use communication options(email, messaging, G+/Facebook/Twitter)
all things considered, the only serious hurdle that needs to be cleared is the last one. the other 4 will help it sell but app selection will KEEP it selling.
