At first, I was super overwhelmed by how the navigation and such worked, the "app" system is weird but innovative. I feel as if I'm messing with my Android phone.
After the first few minutes of tinkering, uninstalling and reinstalling certain programs, I've come to enjoy it's simplicity and resource-efficiency. It definitely makes my browser run a lot faster (IE10).
Right now I'm hopefully installing Google Chrome, and seeing if that is compatible. But thus far, if you're willing to tinker a bit and figure it out, it's a good step for Microsoft. Windows 7 is still a great OS.
As I sip my now-cold-coffee, I'm gonna take my Grandmother to her doctors appointment, then get back to pixeling.
(Side note: IE10 works best with Windows 8, which is surprising and awesome.)
