Are credit cards all that bad?

I started my credit write after HS in 2011 when my I co signed with my mom for my new car. All payments so far have been on time so I assume my credit is very healthy so far.

I recently applied for a credit with Barclaycards, they work with Apple, to buy an iPhone 5 no interest. I have a job. I've done the math and it would be $55-$60 a month. Personally I think that's easy to keep up with. I would get charged interest only if I miss a payment. My parents have been against it but it boils down to my decision. I'm 20. I think it can help build credit if anything.

Personal opinions?

Added (1). I do have a job. And yes I now about the deadline. The purchase I want has a no interest within 365 days.

I need mac/itunes/iphone/music

Ok, so i have an iphone, had music transferred from my moms pc to my phone. I recently got a mac mini for my birthday and i want to copy the music i have on my phone, to itunes on my mac. When i plug my phone to my mac it says it will have to delete all the songs on my phone, and i don't want to do that because the mac doesn't have a disc burner, and i have a few cds… So bottom line is, i want to copy songs on my phone to iTunes on my mac so i can play them from my mac.

Would This Business Succeed or Fail?

I'm 16, and I have motivation to start a small business. I currently own a MakerBot 3D Printer, and I have 3+ years of experience working with CAD (Computer Aided Design) software to make practically anything possible, from cars to small parts. I would like to open up a small business that can make various cases & accessories for the most popular consumer electronics. From iPhone cases to basic feature-phone cases, all different types of these cases for practically every phone. I can easily access the dimensions for all different types of devices. The difference with my company would be that these cases would be completely custom. Choose a color, and a completely unique design. The consumer would send a drawing/picture with a description of the design to the business e-mail, and then we would create the rendering, send it to the consumer, and then if they approve, they pay using paypal, we create the case, and then ship it. I'm not confident that this could be profitable.

How to get music off of my new computer onto my iPhone 4s?

The catch is, I can't get to my old computer, the one that has all my original songs.
I've already figured out how to get all of my songs onto the new computer, but I can't put new songs from the new computer onto my phone.
I reset all of my authorizations and the phone is only authorized on the new computer.

Please help I'm stuck with outdated music! :/ :/ Thank you!

What should I wear to Six Flags?

Next Sunday I'm going to Six Flags Discovery Kingdom, and I don't know what to wear. Last time I went, what I wore was a huge disaster. I'm planning on going on all of the rollercoasters and the water rides. That makes it just hard. Sneakers are good for the rollercoasters because they won't fall off, but then they're not so good for water rides. I want to wear Nike slip on sandals with socks and then just wear socks on the rollercoasters and then on water rides take off the socks and the shoes… But I don't know? I want to wear socks and a loose tshirt. But the SHOES are what are giving me trouble.
Plus what do I do with my iPhone? I'm goin with my bestfriend and her family and I don't know if the rest of the family is going to be with us. Her mom and younger sister aren't going on the rides but we're, but I don't know if they're going to be walking with us everywhere we go. But even if her mom is with us, I kind of don't want to give my phone to her because I would like to have it while we're waiting in line and stuff. Because some lines are super long and I can't go without having my phone for that long(security feel)

So help with my phone/money(mostly phone)
And SHOES to wear? I don't really care if my feet hurt.
