Finally, Apple is a company that prefers simplicity in its product lines. Right now the company is selling six different iPad models. That's got to chafe a whole lot of people in Cupertino. And it's a product line that can be simplified by eliminating the concept of a Wi-Fi-only iPad.

Embedding cellular connectivity in devices is the future. I'd imagine that, by this time next year, every iPad Apple sells will include cellular-data access. (It'll certainly simplify the product line.) In the meantime, the question remains: Save $130 and cut yourself off from the 3G network, or spend the money and keep your options open?

For a lot of people, saving the money will be the right call. But the 3G deal is so good that I'd give those higher-cost models some careful consideration first.
