No!
I'm 12 and got the original iPhone last year for Christmas, my parents pay the monthly fee while i payed for the handset.
For my birthday and Christmas present this year I got a MB,
I'm not spoiled as i pay for my own stuff and imo in the UK it's the norm for a senior school child to have an expensive phone and their own laptop.
Don't listen to people who say you're too young, their just narrow minded people who are stuck in some old forgotten decade!
IMO, aslong as you pay enough towards it and don't go round showing it off (within reason) then you and I are perfectly fine to be so lucky in owning such great pieces of technology!
