Is the iPhone 7 really worth buying?

I'm an android user. However, I have a lot of questions about the new iPhone and what people think of it. There's people who think the iPhone 7 is awesome, then there's others who think it's a piece of crap. If you have an older iPhone is it worth the upgrade? What if your looking into getting your first smartphone and were thinking about getting it? Is it worth it or is it smarter to get the 6S? I'd love to hear what people have to say about this!

Do I include the SIM card when selling my old iPhone 6 on eBay?

I got a new Android phone with a different carrier, so I have no use for my iPhone 6 which is on Straight Talk. I'm going to remove it from my account and sell it as a carrier-specific phone on eBay. My question is, do I also include the SIM card that came with the iPhone or is the buyer supposed to buy their own? I don't know whether or not you're supposed to include a SIM card because I'm not sure if any of my personal info is associated with that SIM card. Thanks!

My computer keeps scrolling down on its own and I don't know why?

My Windows 7 laptop all of a sudden today keeps scrolling to the bottom of the screen. For example when I try to scroll up to the top of a webpage the page it keeps going down and no matter how many times I try to click to the bottom it keeps going back down again. What should I do? This is really pissing me off. I'm asking this question on my IPhone that's how bad it is.

I got a weird text message and I do not know what to think of it?

On my iPhone 6s, instead of a number, it says the contact is esqmk404& I've never replied, but I still have it on my phone because I don't know what to think of it.

Here's what it says:

"Be informed that your phone number was found in your documents as his next of kin contact me via, for details"

I think it's someone suspicious because what person would have an email like that? Plus, they do not make any sense. "As his next of kin"?

What should I do? Just delete it?
