Somehow people manage to buy cars. Its an example of making decisions on expensive technology without actually using it in one's daily life. Tech companies have encouraged the try to buy practice with liberal return policies. I am only pointing out the waste involved and how it could easily be avoided. I am against waste and for rational decision making
I don't drive, and have never bought a car, so maybe there are nuances involved in picking a car that I'm not aware of, but seems to me that despite the cost, a car is a simpler technology than computing devices. I understand that car dealers let you test drive cars, and I imagine you can put a car through all common driving scenarios during a test drive. Am I wrong?
Now that I'm thinking about it, I think looking and playing with computing devices at a store is like looking at a car in a dealer's parking lot. You can sit in the car seats, play with the switches and the seat belts and door and window controls, etc, but you don't know how the car handles without taking it for a drive around the block. And I think mobile computing devices are like that. You need to load it up with apps you are actually going to use, and carry it around for at least some hours to see how it fits into your daily routine.
This is not the same as with desktops, because desktops are pretty much the same as long as the main cpu fits in your word space, and the components you directly interact with, such as keyboard and monitor, can be switched if they don't work out. With laptops, I spend time testing the keyboard and pointing device, because they can't be changed, but spending some time at the store is enough to get the feel of the keys. Tablets and smartphones, you have to spend time with them, especially if switching to a different size. I know I would have really hesitated buying the 12.9 iPad if not for the return policy, because I had no idea if I could get used to such a big tablet. And I'm glad there was a return policy so I could spend the time using it at home, knowing I could return it if it didn't work out. And I did eng up keeping it.
