A:
Do you know where your son-in-law is going to be? On larger bases, there is access to WiFi at an MWR building, at least. If he will be on a smaller base or near a big city (Kabul, Herat, Kandahar, Jalalabad, etc), the Kindle with 3G would be a better choice because it actually works with the cell towers here. I just purchased a Nook Touch and use the WiFi at my base which works very well. Very happy with the Nook.
