Re: The Half-Truth
A lot of people who speak positively of Windows 8, either completely hide Metro by using 3rd party tools to restore the desktop to Windows 7 / XP functionality, or are at the other extreme and want to see the desktop phased out, with a complete Metro interface. Casual users may find either of these two extremes usable, but jumping from one to another, with no clear pattern between them, and relying on hot corners, and hidden bars to activate things is certainly not going to endear them to it. Nor is having to remember the name of programs, to search for them, or a ton of keyboard shortcuts, which those who like Windows 8, suggest make the best ways to nagivate the system.
An entirely Metro-ised system might indeed be easier for the casual user. However once they try and do any sort of proper work, or indeed need to organise their files, the interface shows its weaknesses. And having a completely different style of interface for these tasks, is not making it user-friendly.
Linux distributions which keep the familar XP style user interface, are going to be a lot easier for casual users to make sense of, than Windows 8. Indeed one could argue that the 'Start' menu in say Linux Mint is superior to Windows 7, because it effectively categorises programs by their type, rather than manufacturer.
Incidentally, one of the reasons desktop Linux is criticised is due to the perceived lack of applications available for it (note: I said perceived, I have found plenty of decent software on it, and as many people have said, maybe the introduction of Steam might be a step to change these views). It is worth pointing out that Metro has no killer or compelling applications. Most of the reports on it appear to be about Twitter and a lack of Facebook 'apps', which may be an issue on mobile platforms, where bandwidth is at a premium, but on a fully fledged desktop with web browsers, is quite frankly crazy.
