In my opinion, Windows RT is a missed opportunity. It should've been the replacement of those "Linux" or "no OS" variants on laptops and desktops. After all, the user couldn't go anywhere but spending their money on Windows Store anyway. Google survived that way. At the same time, Windows RT makes a great OS for half-computer-literate people. I mean, it has Word, Excel, and PowerPoint, it cant get viruses, no antivirus required, no malwares like "PC Optimizer whatever", "Get Free Games whatever" or "Google Chrome". That sounds a lot like the perfect OS for those people. Yet, Microsoft limited it to a small tablet with ARM CPU, a device that those people wouldn't buy to replace their laptop. Had Windows RT shipped with $300 laptops back then, Chromebook would have no traction at all by now.
