I guess. In that case, I cant argue. It only makes it an even poorer financial decision to me. I certainly wouldn't buy an iPad as well as a perfectly usable laptop. But then I'm not the market Apple are targeting.
Definitely, if you needed to update your hardware for laptop usage then I can understand why people do that instead. The price comparison compared to usage would make it silly to have an ipad and an old outdated laptop

My biggest worry about getting an ipad is that I would never get to use it, my wife and my boy would be fighting over them!
