I just have two gripes with Window 8.
The first is the following:
Windows, get your damn tablet OS out of my damn desktop and laptop computers.
Sure it might seem like a blast if you have a touch screen interface device (or nothing that resembles a sensible computer), but for all of us who just want a competent OS for our "giant machines" that are questionably portable, we like to have something that works, we're familiar with, and that we can jump right in without having a tutorial chained to our ankle.
The second is that this just wreaks of laziness. Yes, I get that Windows feels it needs to create a new OS every few years, despite people being happy with what they are currently using, but what happened here? They just ported the tablet OS and repackaged it as the new desktop and laptop OS. It's like the PSP interface being ported into the PS3; yeah, it functional, but it just seems silly and a bit unimaginative.
All I ask is that Windows 8 takes a lesson from Apple and allow us to have two modes to work with (i.e. regular Apple desktop and a PC desktop). The first mode will be the standard Windows 7 desktop for sensible PC users and the second can be the Windows 8 OS for douchy, pretentious "Look at me! I have the latest of something so that means I'm popular and relevant!" consumers.
