Future wish for a wifi screen

So my phone can accept streams from a Wifi network , it can play music , show pictures and play films all via the Wifi network

What i want in the future
A
Wifi Touch screen or Tv , that connects to my network and streams all
my content , simple … why not !! my phone can do it and that is so
small it sits in the palm of my hand

Hang it on the Kitchen Wall
and the job is done , it does not have to be a monster size, it should
not have a seperate Pc running it , it should be an all in one unit

As
an extra add on , it could have wifi speakers, the screen looks at the
network, connects and plays back on itself or to wifi speakers ….
again this is exactly what my phone can do , i can play all media on
the phone or i can tell the phone to play audio files from a wifi
connected speaker such as the Philips WAS700
