Iphone 6(or 6 plus ) or ipad mini? Also some help on christmas list?

Right now i have an iphone 4. I've had it for 3 years in October. I'm due for an upgrade but i won't get it till Christmas. I also wanted an ipad for christmas, i told my parents and they said i had to choose between and ipad or an iphone6(6+) so i'm just wondering which you guys think i should get and the pros and cons for both.
also for the second part i need help with my Christmas list. I'm a teen. Things like clothes, shoes, cases, jewelry, movies, accessories ( scarfs, etc. ) i also have my belly button pierced. Website links for the belly rings, clothes and shoes would be amazing but if you don't have websites its ok.
And lastly if your gonna be rude don't even look at this question nor comment. If you don't have anything nice to say don't comment anything at all.
thanks to all the people who arent disrespectful and give good helpful answers.

Why is everything so expensive now?

I was shopping and just started to realize that prices have gone way up. I mean, a few years ago, paying $40 for something was a big investment. And if you bought a kitchen appliance for $100, it BETTER be good. And it was. It was high quality and worked great.

But I was at the mall and saw some stuffed animals toys, about the size of a golf ball, for $10. Wow! Beats headphones are $200 for plastic. And iPhone cases are usally in the $40s for a thin piece of plastic. What happened?

Why is everything a rip off now? Things are getting worse in quality but going UP in price! They make cars with plastic bumpers now! What's that gonna do in a crash?

Has it reached the point where supply is starting to meet demand on the iPhone 6?

A couple weeks ago it was virtually impossible to obtain unless you ordered it (which meant a month's wait), or decided to pay a higher price on eBay.

Recently someone I know just walked in the store and bought one. They got lucky as there were only a few left and there was a line of people. Then yesterday I tried it and was able to get one by walking in, despite there being a line. Granted, they sell out quickly and only a few were in stock.

In a couple weeks or so, will it be relatively easy to find them in stores?
