Windows 8 works well on smartphone, tablet and everything else with a touchscreen
Alas no desktop or laptop has touchscreen and what planned for touchscreen commands doesn't work well with mouse command
If you are not used to smartphone will be a nightmare , but also if you are you will risk at first to get mad fighting with a zoo of undesired apps that apparently start by themselves and once started can't be closed , and the mouse that never does what you wish .
I found a cool Open Source program Classic Shell
http://www.classicshell.net/ that solve most of problems and has also a simple and clean interface and is easy to use
Most is detailed here
http://www.classicshell.net/ But one of the most precious feature is not highlighted there :
Win 8 use the 4 corner as "hotspot" the idea is that moving your mouse there you switch back from the program you are using to the "apps" screen or open a large lateral taskbar or ...
Again maybe that works well with touchscreen, but on laptop screen the hot corners are over-sensitive, so any movement in direction of the corners will bring away from what you was doing, back to the "apps screen " starting point
Making basically impossible to use programs at full screen :
all program's controls close to the corners ,i.e at right top the "-" to minimize, the "X" to close ,and "File " "Edit" "View" in the left corner will become unusable :
any attempt to click one of them there will instead activate the closer "hot spot" ,usually bringing you back again and again to the "apps screen" starting point .

Luckily "Classic Shell" allow to disable that "Hot Spot" nightmare (its functions remain accessible from keys , without disturbing) with just 1 click
Super ... it really makes Windows 8 usable also on Desktop and notebook
personally i went farther and found how permanently unistall all the apps, permanently because if not Windows will reinstall most when updating ...

, but that mostly because i deeply dislike the idea of dozens and dozens of apps that i would never use running in background , wasting my storage space and ram
