Never had an issue...
.. with Microsoft products - especially Windows 10. Looking at the OS from a home user perspective, I'm not sure what people have issues with? I think the UI is perfectly acceptable and quite intuitive, with a few areas that could use improvement - the two different 'Add/Remove Program' windows maybe? I think Microsoft have a chance of building a fan base with their new Surface range. Owning a Surface Pro 3 myself, I couldn't recommend it highly enough. The whole telemetry thing is nothing new and certainly not limited to Windows 10 or even Microsoft products - who the hell is deluded enough to believe that? Microsoft seems stuck with those who resist change, where as the likes of Apple have an army of fans who embrace it.
