The UK software maker Canonical has repeatedly tried, with little success, to position its Ubuntu OS as a platform that works across devices.

The Galaxy S8 runs on the latest and fastest Snapdragon 835 chip. Apple's A-series of mobile chips are at the point where you can at least put them in the same conversation as an Intel desktop processor, and last year Microsoft showed how it can run its full Windows 10 operating system - albeit partially through emulation - on a Qualcomm Snapdragon chip. The thinking behind it makes sense: The smartphone is the most popular way people access the internet, and the technology behind it is only getting more powerful. Tech people call this 'convergence,' or the idea that a single gadget - in this case, the smartphone - can swallow all other device types and become the One True Computer for whatever you need. Samsung is just the latest in a string of tech companies that have tried to sell phones that can also be PCs. Given that the Galaxy S8 isn't cheap, either, Samsung is pitching the DeX as a neat, productivity-boosting extra for Galaxy diehards more than as a core aspect of the phone. Samsung says the DeX dock will cost $150 and launch in 'late April.' So it's a bit pricey.
