I'm sick of installing software.
I'm tired of clicking Next 6 times and waiting for dll's to be registered. Why is it random people on the Internet can assemble portable versions of Photoshop but Adobe can't? Anyone?
I'm tired of being told I have to uninstall old versions of something before I can add a new one. See above. Also - mobile apps.
I'm tired of lousy software provisioning for desktop software getting in the way of me doing stuff. You have to download an update to fix a bug? That's nice. I've got shit to do.
I'm tired of having to configure software, what's the point anymore? Just figure it out. Is it really this important to ask me this now? Can't you ask me later if you think I need to know? Or just make it obvious. How would I even know half this stuff in advance when I haven't used the app before? And if I've already used it and am upgrading.. well you should have updated yourself and kept my settings.
Service pack? What? Update thyself.
Seriously, why is desktop software so far behind? Where's Steam for Enterprise?
