My biggest gripe outside of start, is the fact that default apps are those damn metro apps which rip me away from the desktop. I find it rather infuriating to use Windows 8 for any length of time. I just find that I am always more or less frustrated.
I was on a Windows 8 box today, and needed a screenshot. Usually, I click on start, run and type snip and it's there. On 8 I had to hit the Windows key and jump off the desktop, then type snip, then click it and snapped back to desktop. So, while not more steps it more time consuming...I found it utterly annoying, distracting and it made me a bit angry. Am I being irrational?. Yes. But it's honestly how I feel. I know I am not alone. Had this convo with quite a number of people at work.
What? That's the exact same thing as on 7. Hit Start, type snip, hit enter. Same process on Windows 8, different UI. But again with the apps, just remove them and make a full screen full of Desktop apps.
I don't know if something irrational can be considered a legitimate complaint....
Also, were you trying to take a snippet of something or just a screenshot? Because that's easier on Windows 8, Start key and PrintScreen, bam, that's all.
