Win8 'problems' are far simplyer in nature than typical linux problems. Every development with GUI is going to require a learning process.
In that case I should go see a doctor for my brain seems to be petrifying. When I tried Ubuntu for the first time several years ago, I had no major problems to find a device manager, program installer/deinstaller or shutdown button during my first trial, not to mention a bunch of other functions and features. With W8 I would've been in trouble if I hadn't learned some keyboard shortcuts which I consider being "heavy user/pro tricks". The Finnish Fast Guide to Win8 has not been published yet, so the only source for learning the GUI is the Internet. I agree, MS seems to have the basics quite well documented, but there's always the big "but": What if this is your first computer? How to install a mobile broadband device in between the tiles? What if, like it was with my first experience with W8, the mobile broadband only works on GPRS, making using the net a PITA? If the instructions to access the Internet only are in the Internet, what can you do?
Almost every device or even their packages must have warning texts and user's manuals in the language of the country they are being sold in. That doesn't apply to operating systems: If you buy a pc, there's a warning that the plastic bag can be dangerous if it covers your nose and mouth. The manual tells how to place the rig to avoid overheating; it also tells the names and places of every jack and knob. Heck, even my keyboard has a warning sticker on it, saying prolonged use of it can cause injuries. At first boot, you might get a screen telling how wonderful your new computer is. No "Read this carefully before doing anything else with this computer". No safety instructions, or warnings about losing your money, identity, reputation... Just a happy "start exploring!" -at your own risk...
