What are some good gifts to ask for christmas? I've only thought of a few, but i really can't think of some!?

So i really want to have a good list of some things that i would like this year for christmas. I am 16 years old, 17 in bout 2 months. Anyway, my grandparents asked me recently bout what i wanted and i couldnt tell them because i hadn't thought about it yet! So far i want maybe a digital camera because i love taking pictures, or i really really want a cute juicy coture purse even though i know those are more expensive but i really dont have one nice designer bag so i thought that would be sort of fun. I was also thinking about christina aguilera cd's and one of her piano books with sheet music, and some pj sets with slippers like the cute ones from victorias secret. it might sound like i already know what i want but i just want some more ideas. And for movies idk which ones yet but i will want movies for sure! It just seems like their is so much to put down. And i told my friend allready i wanted some nail polish with those design brushes because i tried them and they work really well! so please give me some more ideas :D.
