Hello, I am new to this forum. I am planning to buy an ipad, but am unsure about a few things. I have a 16 GB iphone 4s, which seems sufficient, but wonder if that is good enough for the ipad or if I should get 32 GB? Also, besides the obvious, are there any advantages to getting 4G network, or is wifi enough if I have it at home? I am planning on moving to Europe next year, and am aware that 4G is not available there and also know nothing about data plans, and so am leaning towards just the wifi. Thanks for any help on both of my questions.
