I couldn't really watch it, unfortunately, but the general feeling I saw on Twitter was that this was a vast improvement from last year's WWDC.
Gizomodo has a nice round up of the features announced. HomeKit sounds VERY interesting... it'll be fun to watch vendors try/not try to take advantage of that. And integrating Shazaam directly into Siri is pretty cool - but are people really hearing music that they don't recognize when they are out?
I'm thinking of starting up a project that will require me to stream video from a laptop stationed outdoors, far away from any WiFi network or hotspot. I've thought about using EV-DO (like Verizon's Broadband Access)
