Question: Are both displays touch or only the outside tablet display?
Document: The touch screen still functions when the touch-screen display is powered off.You can run three displays from this device, that is two external displays, and the laptop screen. All 3 displays show something different, something not possible with many laptops.
A switch on the side would be the solution but I'm assuming Asus doesnt want to be sued by Apple for that ;)Virtual keyboard doesn't show up when you need it at all times. Specially when tablet is locked  and nees to enter the password sometimes you need to  use the laptop keyboard.Switching displays. There is a key in the keyboard to switch the different display modes (laptop only, tablet only, both mirrored, both extended).
So, not really needing touch outside of tablet or presentation mode. Also, no instruction on the stylus, had to look it up online. The battery life is not to good when charger is removed but it's not that bad either. Also, DO NOT update to win 8.1 the tablet mode doesn't work. Funny how all the reviews show up after you make a mistake. Anyways it was easy to restore but nerve racking while you pray it works.
Taichi does just this.Turn the laptop around hit the outside screen switch and I have a tablet at the angle I want and can watch movies or still just use the tablet as it was meant to be used.I hope this is making sense to some of you.To summarize, I don't want a touchscreen when typing and doing emails and regular laptop functions. I do want a tablet when I can touch it easily, write, swipe, and draw properly.
Pro: Excellent Display, Design, Layout. The backlit keyboard is a very usable feature. Boots fast. Easy to setup and use, first-rate battery lifeCon: PC display should be a touch screen like tablet, Wireless is slow when using remote desktop (compared to my much older notebook running XP pro &#34;could be windows 8 issue&#34;), Second USB will not work correctly with Asus Blue ray external drive.
And for now this is the only form factor that is out their that works the best, until the Lenovo Helix and the HP Revolve comes out, outside of that I am not sure whats out in the horizon, but I am sure ASUS will have an improved Taichi or a different named PC that has dual touch screens.
I really like the dual screens, because the outside touch screen does get full of finger prints. For those of you that are wondering mine came with the stylus and the case. The stylus works very well for my use (I use it for taking notes). It was a little expensive, but only about 100 dollars or so more because you do get the extra screen.
A had to return a Taichi because the touch screen kept registering false taps in the top right corner. This was stupidly frustrating since it messed up my gesture password and would randomly close programs. Imagine browsing the internet when randomly 10 blank tabs open. Having to return a Taichi for this reason just makes me question the outside glass surface even more.2. I had to return my second Taichi because the battery kept losing life. After two weeks of use the battery wouldnt charge beyond 89%.
Getting a Core i7 Taichi with a 256gb SSD for several hundred dollars less than a Core i5 Helix seemed like a good deal, so I purchased.The machine itself looked and felt great. Some people don't like the dual display with the non-touch interior screen, but if you order this, you know what you're getting. For me, the trackpad worked fine for gestures on the interior matte screen. Also, typing on the keyboard was smooth, and the matte screen was easy on the eyes.
DO NOT BY A TAICHI ! - The outside (tablet) screen on my unit has never worked consistently. I spent innumerable hours with ASUS on the telephone, before they finally decided it needed to be sent in for repair. Yes ASUS pays shipping, but you pay packing costs and spend your valuable time going to Fed Ex. Got unit back. They did not even say what was repaired, and did not return my tablet case! Outside screen worked for about a week. Called ASUS back.
Answer: Only the outside tablet display touch, not both sides.
