Ever since the iWatch rumor began I wondered about whether Apple would actually do it. I tried to think of what an iWatch would do that would make it necessary. In order to make it Apple will need to sell it in large qauntities for it to be worthwhile. It most likely will be expensive since Apple doesn't do cheap so again why would anyone pay for it. Then today I started to think about a few things and I had an epiphany of sorts. Well at the least a very plausible idea I think. The one thing I always though is the iWatch has to do something that will save the user battery life on their iPhone or iPad. It also has to be something that goes beyond what their iPhone or iPad already does. An example being able to control the music player is not something that would make people spend a large sum of money for an iWatch. Then I thought what is one of the drawbacks to Siri? The activation method, holding down the home button, Siri would be much more fun, natural if you could just call out "Siri". But having the iPhone or iPad always listening burns up battery power. You probably already see where I'm going with this now. What if one of the big features of the iWatch is that it's always listening? It uses less power and does less than an iPhone or iPad. So if when linked you could just say Siri and the watch would activate Siri and you could ask/schedule/call etc. Would that be something that would make people willing to buy the iWatch? I'm still kind of iffy on it but that's just me though as an additional feature it would make me salivate for it. It would be like the iPhone 4 compared to the 4s in terms of not having Siri. Once you use it not having it just didn't feel right and you want to have it.
