The race of technology

I recently saw this commercial on television about this new phone that is coming out that has a projecter attached to it. I thought to myself, when and where would I actually be able to use that kind of thing? I think sometimes most phone companies try way too hard to compete on who has the better and more advanced technology. I mean, hey, I don't blame them. They are just doing what needs to be done, but you won't see me running out to buy something like that.
