Why do people want the new iPhone?

I went to go look in the apple store the other day, and a street full of people where camping there, with there macs and iPads and sh! T. And everyone was fighting to go in and get this iphone. Today, I was going somewhere. We've happened to pass by the apple store and there's still a big hell of a line. What is with people these days? And why do they want a crappy iPhone 6 or iPhone 6 plus?

Ios 8 download about 40 hours remaining?

I've been trying to update my iphone 5 to the new ios 8, but after clicking download and install on my phone the time remaining changes between 25 and 60 hours when I check the update screen.

IPhone battery/water damage?

I have an iPhone 4S the last nine months but only had 3 months warranty but it has been workin fine since I got it but the last week it's been turnin on and off it randomly comes on when it feels like it. I think it might be water damaged or the battery could be overheated because my phone was off and wouldn't turn on and it was vibrating and the battery was roasting hot?! I brought it into a guy who repairs phones and he said it can't be fixed but it's working now the only thing is I'm not sure how long it will last, it never lasts more than an hr, is there anything else I can do?
