I bought an HTC 8S back in February and the screen cracked on the 20th. I wanted a new phone because I know that if I dropped it again, the screen would become unusable. I couldn't resist the Nexus 5. I paid $399 + tax & S/H for the black 32GB model and I couldn't be happier. Coming from a 4GB device, it's nice to not worry about installing too many apps.
The first thing I noticed was the display. At ~445 pixels per inch, individual pixels are damn-near impossible to see. The colours are great and the viewing angles are superb. Also, Android 4.4 is amazing. Windows Phone 8 has its strengths but at this point, Android is superior. I love WP8 and I want it to be the #3 smartphone OS but Microsoft has to improve a lot of things before it comes popular enough for companies to make apps for it.
Anyway, got any app suggestions? I've installed a bunch so far but I'm curious about the lesser-known ones.
