I have one question for Apple after yesterday's presentation: How in the heck did you forget to mention Apple SIM?
The revolutionary new SIM card -- which was first pointed out by 9to5 Mac, was not mentioned in Apple's keynote, and which only began to make waves on the tech blogs later in the afternoon -- could revolutionize how you connect your tablet to cellular data.
How? It allows you to hop data networks when you don't have coverage, or when one carrier is offering a cheaper price, or when you travel to the UK. It is, in essence, a cross-carrier SIM card that supports AT&T, Sprint, and T-Mobile in the United States and EE in the United Kingdom, with hopefully more networks to come.
