Who has played the Deus Ex 2 Demo?

i downloaded this morning and finished it in a half an hour. It did dissapoint me I had such high expectations.
1. I have a p4 2.6 ghz 512 mb memory and geforce3 ti200 card, cant play without framerate dropping on 640x480 resolution... I guess time for new graphics card radeon 9600 xt maybe
2. aiming sux the mouse is completely fucked up IMO, I dont know but it just doesnt feel right
3. I didnt get the "deus ex conspiracy,freedom feeling" at all. This could be because u get dropped in the game without any idea of whats going on, u just get an assignement

I'm just gonna w8 for the full game and play that. But I had expected more of this
