Of course the first model will be good BUT, just like iPhones and every other new technology that's ever been released, each year they'll release new models which are faster, better, longer battery life, lighter, smaller, better cameras etc etc. It's how it works with EVERYTHING. It also encourages people to keep buying new ones. The first Windows or iPhone or anything wasn't that great in hindsight but at the time it was awesome because it was a new technology that allowed you to do things you couldn't previously do. Their will be a HUGE market for these worldwide.
