Like Marketing said that Consumer are always variety and different. For iPad2, there are people who think the 3G model is only the correct choice to buy while there are still other people who think that the Wifi model is enough and also better in save money. There are people who prefer black model as always and also people who thirsty for only everything in white. There are people who buy only the biggest 64Gb model and people who think the smallest 16GB is the correct way to go, while still there are people who think the middle 32GB model is the most suit choice.
This is basic but it also make me surprise from times to times when see it in real life. Cheers, marketers! 🙂
