This graphic guide will tell you which model is the perfect iPad 2 for you, depending on where and how you are planning to use it (click on the image to expand).
What experience told us
When it came out last year, nobody knew which iPad to buy. Everybody here got the model they thought would work, but nobody was sure. Now, after spending almost one year with it, we know exactly what we—and you—need.
For example, Chris Mascari and Brian Barrett spent extra money on the iPad 3G but, after using it all this time, they discovered they rarely used the 3G connectivity. Every time they used their iPads they were in their houses, a coffee shop or a restaurant, where Wi-Fi is almost always available. They are now buying the Wi-Fi model.
I bought the iPad Wi-Fi 64GB. Like Chris and Brian, I rarely find the need to access the internet on the iPad unless I'm sitting down somewhere. And generally, as a person in New York, that means there's likely Wi-Fi.
Who really really needs 3G connectivity
But none of us here are heavy commuters. My home is close to the office, so I use the NYC subway—where, surprisingly for being the capital of the world, there is no 3G service yet—for only a few stops.
The only people who actually need 3G connectivity are: a) those who commute a lot and don't have a Wi-Fi connection in their trains or buses and b) those who really need to be connected at any time in any place, in the middle of a park, a road or the street c) those who travel a lot without a laptop internationally or domestically d) those who don't live in dense urban areas without Wi-Fi everywhere e) people who think an extra $130 is not too much to pay for insurance to have it when you do hit the road and think tethering to a smartphone or Wi-Fi hotspot is too annoying to do every time you need to have a connection. (Which is now a viable option for iPhone-owning iPad users with personal hotspot powers in iOS 4.3.) If you belong to any of these categories, then the 3G is a good option.
The other deciding factor is the GPS. None of us have used the iPad for true GPS location services. In cities, Wi-Fi geographical positioning works perfectly well. Those who need real GPS in the car or trekking may need an iPad 3G. However, a smartphone will serve that function better than the iPad, since they are smaller, lighter, and their form factor and screen size is good both for cars and walking.
Black vs White?
It's kind of one-sided. All but one of us chose black. Here's why.
