I'm having trouble understanding what the point of this product is. What useful niche does it fill?
In a fully managed enterprise environment, using OneNote to take handwritten notes in meetings - including creating quick To-Dos to send to Outlook, using handwriting to mark up Excel, Word, or PowerPoint files stored on a collaboration server so everyone's changes are synchronized, then go back to your desk and dock it so you have a full keyboard, mouse, external monitors (I have two), auto-switch from corporate WiFi to corporate LAN without losing mapped drives. In the enterprise space its competition is likely a Lenovo Helix model, not a Miix. For home users, it's probably overkill, unless maybe you do a lot of docking-and-undocking at home, but that's likely a niche market.
But if your company, like mine, allows a certain degree of personal use of the corporate device and allows you to take it home evenings and weekends, it's a lot lighter to carry and more fun to use than a traditional laptop. It's my laptop at work and my tablet at home (and yes, I know how to encrypt and back up my personal data in case my job suddenly disappears, and I still have a home PC as a second unit). It's the most satisfying and seamless personal computing experience I've ever had, and I've been in the business since the 1980's. This feels like the computer I've been waiting for all my life.
