"Ale urwał" xD ha ha ha ha
No, i will not upgrade, pointless to me, brings no performance boost and because of moder ui is unusable to me.
Of course, windows 8 has some nice options which i like but modern ui is absolutely not ergonomic and annoying in work and common usage. I like ribbon in explorer, copying/moving files, task manager but it is not enough to make me jump into moving blocks
I'm not such a tetris fan
If windows 8 sells will keep in current state they will add ribbon to explorer in windows 7 and also will bring to this one task manager from windows 8.
