Am I spoiled? (11 years old)?

Sometimes, I feel really uncomfortable around one of my friends because she always gets what she wants. Even though she doesn't brag about it, I still feel jealous that she has so much that I don't have. The other day she was complaining that people said she was spoiled, and that she isn't. I told her she was a little spoiled, but now I'm scared that I'm the one that's spoiled.

Here's what I own/am allowed to do:
One touchscreen laptop (Our school forced each person to get one)
A iphone 4 (Hand me down from my dad, 300MB per month if I pay it myself, and I have to pay for my own phone fees)
A old laptop, non touchscreen
A Piano, just those normal ones, not the grand ones
A kind of special table that if you accidentally draw on it you can rub it off, three years old
Around $80 per month for my lunch, and $25 for my allowance
I'm allowed to go wherever I want, but I have to be home by dinnertime unless its like a birthday celebration or some party my parents have approved of

Please answer guys I'm so scared that I'm the spoiled brat everyone hates

Spoiled is an attitude not what you actually have. Not being happy with what you DO have is a sure sign of a problem.
