Obama's Goal: 98% of US Covered By 4G
4G technically refers to networks that have "peak download speed at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users)" http://www.itu.int/ITU-R/index.asp?category=information&rlink=imt-advanced&lang=en
Wireless broadband services offering WiMAX (clearewire, DBC) are not technically 4G (unless implementing 802.16m), but are still "mobile broadband" as of 802.16e.

Do High Schools Know What 'Computer Science' Is?
I disagree. Teaching students the tools of the trade (IDEs, debugging, control structures, if....then...else) are the foundations of the Science. You are taught math the entire time in high school, and an advanced math program starts with the assumption that you know how to add, subtract, multiply, etc. Teaching kids, either in high school or CS101 gives them the tools to move onto and understand Binary Trees and Linked Lists..
No Love For The Blu-Ray
Sony can't seem to win for losing. They were doing ok, at least in my mind, until the DRM root kit, and it went downhill from there. Blu-ray is just another straw on the camels back. I have to wonder, how much more can the market take?
