I have one
I picked one up from John Lewis when they first came out.
Am not sure about the Windows vs. Linux debate.... Anyhoo, I must agree with most of the comments from the original review: Lack of backlit keyboard is a bit of a pain, it is rather heavy and yes it is trying to do lots of different things and not all of them entirely successfully.
For me: First and foremost I wanted something to replace a bulky desktop and to connect to an existing monitor. I also wanted an occasional laptop and the use of a large screen Android tablet. So, in my order of priority the Trio works well. More often than not the tablet / screen is disconnected, and only occasionally used just as a separate Android tablet, although Android does actually take longer to fully boot than Windows 8 with an SSD. The Android / Windows integration has been much lauded, but I must confess that I have not even tried that; I can save shared files with Microsoft or Dropbox, and I don't have a huge list of websites to share.
However, it could really do with an SD card slot and despite the 2x USB3 ports, docking stations are still a bit light on the ground (none available with SD, why not?!). There is a slight whine from the fan when it has been run for a while but not that bad, hopefully it doesn't get worse over time. Also, there can be issues with OS switch / screen drivers, hence why I have resisted Windows 8.1. With this being such a niche product I wouldn't be surprised to have to wait a long time for them.
I had actually been holding out for the Thinkpad Yoga, but I think the screen would have just got in the way when it came to using it with the external monitor. Yes, I know £900 is a bit spicy but it's still cheaper than the Thinkpad Yoga and for what I want I'm am very happy with my purchase.
