We have a Samsung with the 10.1" screen. Thought the 7" was a little small for reading webpages and the like. It's wifi only, but if you have a smartphone, you can downloaded an app that makes the phone look like a router, and you then connect to that (very simple) and have wifi everywhere you have phone service. DO NOT PAY Verizon for that service, it's absolutely free by downloading PDAnet+ from Google Play. Use of it applies to your data plan, but that's 2 Gigs which is way more than you'll need in a month unless you're streaming movies over it or something.
The only bad thing about Samsung tablets is the pre-loaded******on them that you cannot remove. I don't know if Apple does this or not.
