I got mine new iPad from Verizon, the 10 dollar a month thing is what I pay. Covers everything. I do the edge program, so I get the new iPad every year, or when 60% of it is paid, I upgrade. The 10 dollar program they have covers more than apple care. Since apple care comes with the device for one year, I will be upgrading by then anyway.
Before the edge program, I would have never thought about buying an LTE iPad. I would just stick with wifi and go cheaper.
But considering, I get a new iPad every year, and I only pay 30 dollars a month for a 128GB with LTE, it's worth it.
Always get Applecare on your Mac's though! I made that mistake a few times. I got to remember to get it on my new retina macbook pro before the year is up.
