searching the web to find techniques that should be intuitive is not a good solution. I think you're going out of your way to apologize for poor usability design.
Now proven wrong, you adjust your complaint from "non-existing predictive text" to "non-intuitive default options". Basically you don't have an actual issue, you are simply going out of your way to bash Windows 8. Very brave to do so on Slashdot.
For the sake of discussion: default options in Windows 8 are a mixed blessing. As an example, in previous versions of Windows one could pick the timezone during the setup; now like a lot of options it's set by default (silently), which can be annoying. It looks like Microsoft decided to make the setup a lot more straightforward, and this design decision is also reflected in the very basic and user-friendly "PC Settings" page. It has the same feeling as on other OS where a lot of stuff is hidden under the hood. Computers for dummies.
However there is a minor benefit to that approach: since user settings are stored in the cloud, when an option is changed on one device it is changed on all devices where the user logs on. This is no innovation as this was already available on other devices (like Google Nexus) but it makes the issue of default options a bit less annoying; it can actually be very convenient not to have to answer to the same questions every time a new machine is configured.
The tablet experience on Windows 8 is just not particularly great, and it only gets worse when you want to use desktop apps (such as Office, which is what Gates was bragging about).
As for the Desktop mode, I agree that it is not well-suited for a tablet (unless is comes with a physical keyboard, but then it's a netbook not a tablet). The keyboard is not the same and won't activate automatically; using the touch interface for right-clicks is awkward and having to mess around with thin scrollbars is unpleasant. In my opinion it's a poor way to slowly migrate people towards Metro.
But the worse of it all is that Office is not available in Metro, only on Desktop. Same goes for all the big Microsoft applications (Visual Studio, etc). It feels like Microsoft is trying to have it both ways with Desktop and Metro but it's not working, it's confusing.
At the end of the day Windows 8 is not a bad OS and does not deserve all the misinformed bashing it gets. It is pretty stable, has a decent firewall and antivirus built-in, has very effective file versioning features and does a good job of storing settings (and files if desired) in the cloud. But the bashing is typical; every single release of Windows has endless floods of people who don't know what they talk about come out and complaint endlessly. These people are like those commies who keep predicting the fall of capitalism or Baghdad Bob claiming victory on tv with american tanks driving by in the background. It's almost cute.
