What cell phone should I buy?

I want to buy my first cell phone, so far I'm between these choices:
1) Samsung Omnia i8910 (720p video recording) $599
2) Motorola Droid Milestone (Very Slim, great resolution) $500
3) Nokia N900 (Mozilla Browser, Flash 9.4 support, Linux based Maemo OS) $530
4) HTC HD2 (It just looks cool and has a gorgeous screen) $599
5) Sony Ericsson Satio (Camera) $600
6) Sony Ericsson Aino (Camera) $450

P.S: I'm 14 years old and this will be my first phone. Please, no crap about don't waste parents money because I had to win the Delaware Valley Science Fair for this, the tri-state area was mne, and now i want to buy my firs phone with that money, because my parents won't. Oh, and don't say 'Get a PS3' because I already set aside a few hundred to get that.

Thanks a whole lot!
