All - Thinking of picking up an iPad and have a few questions. I have an IP4, is the iPad worth the purchase? I was thinking of a 16G, is this big enough? Considering all the tablets scheduled for release soon, is the iPad worth $499 or should I wait and consider a different tablet. Lastly.. Does Apple offer a hardware discount off of the iPad for Government or Law Enforcement? I looked in the Apple GOVT store and it doesn't list a discount off the retail price? Thanks to all!
