Only run one or two applications at a time...
Here is the problem - you haven't spent enough time with Windows 8 to scratch the surface. Last night I shared a picture to my Facebook and G+ screens where I had a Browser opened and snapped to the left side of the Classic screen, a mail client opened and snapped to the right half of the Classic screen, and the screen split between the Classic and the Modern/Metro Start screen with a news app there in the far right hand of the display.
3 apps all running at the same time (plus other Modern UI apps in the background not displayed), and multiple classic windows open under the screens that were brought to the front. Everything you could do in traditional Windows 7 as far as multi-tasking multiple apps at once *plus* a Modern UI app. It isn't doing LESS than Windows 7. It is doing MORE. Somehow people are misunderstanding the (logical) limitations of the very specific Modern UI app environment/appspace as applying to the whole OS - when that simply isn't the case.
That is, people hear that you can only have two Modern UI apps tiled on the screen at once and they assume this is the limit of Windows 8. It isn't. In classic mode you can do everything you ever could, while ALSO having modern UI apps running TOO, all displayed at once. This isn't being able to do less. No matter how you cut it, this is being able to do MORE.
