By the way someone mentioned you have to launch XBMC/SPMC from the applications menu. Thats not true. Some people are starting to report SPMC showing up on the device in recent after side loading. It did on one of my boxes not the other.
However for the other box i use llama and just use classic tv to launch XBMC no issues.
I have 2 of these boxes and its my favorite. The X7, X8 and others have given me issues and seems like a giant tablet on my screen not a replacement for my satellite/cable box. While i don't use the Prime stuff all the time i do like using it sometimes as its so quick to load. I like the tv apps for it IE history, smithsonian and others. They all work with the included remote no need for an air mouse or something.
My Mother in law can use it THIS IS A HUGE PLUS with the other boxes i had an X7 for awhile and didn't get it and never could figure it out i had to help her. Even in netflix because she didn't understand the air mouse and didn't like using it.
She find her way around the fire tv just fine and doesn't have an issue.
Is it the most powerful box out there? No but it works for me and i have a 2Tb NAS attached and i have no problems playing video from it.
I love the fire tv. Till Fire tv 2 comes out anyway
