Well maybe not, but a day will come when we're able to transmit POWER!, says an old issue of New Scientist Magazine. Until that day comes, this screen has little practical use other than making the Slim cooler. I'm a big fan of the PC Engine, so I kinda like attachable's with little use.

no hdmi?

That's dumb.

Hori put out something very similar for the 360 a few years ago. I think it was the same size screen too.

The screen is to small for me.

That screen has the same resolution as my 32" TV. Man, if only I had waited one more year and picked up a 1080p set as the prices plummeted.
 
Also, they've had these portable screens for practically every console in the past decade. All of them seem so useless to me. If I was looking at gaming on the go with a modern console, I'd get one of Ben Heck's laptop mods, or do it myself.

it looks pretty cool, but im not into that small tv travel type person. All my friends have a ps3 so there's really no need for me to bring a travel tv, the only thing i would bring to a friends house is a game.

i think I prefer Ben Heck's laptop version more.

pretty cool thing. the tv is kind of small.
