Day 2:
Still loving the screen, both the size and the quality, on the Galaxy Nexus. I continue to find cool stuff to do with the OS -- themes, live wallpapers, lock screens, etc.
But as I derive more and more into apps, I'm coming to a realization. There are some extremely high-quality apps (the Play Store for example, as ironic as that might be), but those are rare. From what I've seen, Android simply doesn't have the quality of apps that iOS have. The Play Store might have the same amount -- or more? -- apps than iOS's App Store, the number of quality, polished apps are much lower. Even with apps that are the same (eBay on iOS and eBay on Android, or Flipboard on iOS and Flipboard on Android), the polish is much, much higher with iOS. Smoother, less bugs and more of a pleasure to use.
I cannot place this blame on Android itself, because I have seen first-hand that it *CAN* deliver smooth and quality apps. Firefox, the Play Store, Maps, and more.
This has made me more cool on getting a Nexus 4. Even though iOS is becoming boring -- frankly, beginning to suck -- I spend more of my time on the phone using apps, not fiddling with the OS.
All in all, I really like Android itself. The homescreen is superior, the lockscreen is superior, the hardware is superior, multitasking is superior (iOS's multitasking is, frankly, quite adequate, but Android still is better in rare situations -- for example, try to download a 400 MB file in Dropbox for local storage, then switching to another app for a bit. Yeah. And how you switch between apps? Clearly more intuitive and clearer than the hack-y way iOS does it).
However, I spend a majority of my time in apps, not doing/looking at any of the above.
