I have had great capability and use out of my Acer C720. So, it was no surprise to me that the R13 was a worthy successor. I'm typing this on the screen keyboard now. It takes a little getting used to, but it is nice to have type-ahead like a phone (not exactly the same, but workable). l wanted a Chromebook with touchscreen so I could take advantage of Android. So far it exceeds my expectations and works very well. I didn't anticipate the device having sensors. I thought it would be a "dumb" computer and less like a smart phone. It senses orientation in four directions. Of course it acts like a tablet (in tablet mode), but without the home or other hard buttons. BTW, since I'm typing this lengthy and detailed review, I quickly reverted back to the keyboard since it is much faster for me even though it doesn't have type-ahead built-in (that will probably happen in future equipment and/or operating system upgrades). One thing I absolutely love is the pinch and zoom capability. It is so much easier and faster to set it to see what I'm typing. To me, the lid seems just right. It is not too loose and not too tight. It flips open easily and does not move unless you want to move it. The hinge and plastics are not six-sigma designed and form fitting, but they are very passable for a computer of this price range. I have read other complaints about this being lower quality workmanship or materials. It may not be the top of the line, like the now "near-extinct" Chromebook Pixel (but WAY below the original price; you can get a Pixel near the same price now, but it is already 3 or 4 generations old). The R13 is very sturdy and has a professional feel and appearance. I don't have any problems with lag or slowness so far. The speakers are as good as I could ask for in this package. It won't blow your room away, but it is many levels better than other laptop-style computers I have dealt with in the past. The HDMI capability is good. The video card is capable of 4k+, but I wasn't able to run a stable configuration. It is probably something between the TV, cables, switches, etc. rather than a real problem with this computer. It isn't a big deal for me because I have several other sources to run 4K video. It works fine with 1080P and I'm OK with that. I did get a little scare out of the box as the system seemed to constantly reset itself. However, that was quickly remedied by a Google/Chrome update. I guess the drivers are in bad shape from the factory, but I was pleasantly surprised to see it start behaving well immediately after the update. So far, the Developer Channel has also been stable. FYI: if you want to use Android apps for this computer, as of 12/2016, you need to switch to Developer Channel (Mode) on Chrome O/S (just google for how to do it). However, it is on the list of future upgrades to Chrome and will eventually be on the Stable Channel.
