Copy of iMac or a powerful computer worth its money?

I am reffering to the new hp touchsmart iq 500 series (525).
Its hardware is really powerful considering the Intel Core 2 Duo P7450, 4gb of ram, 640gb hdd, blu-ray, vga 9600m gs hd 512mb, tv, wireless keyboard and mouse and of course a 22-inch touch-screen.
Its desidn is great and the touch-screen i would say is comfortable, but it's a pitty that the system has a blu-ray drive and the maximum resolution of the screen is 1680x1050 not full hd.
So, i am of the opinion that this all-in one pc is worth its money as the version of windows that comes with it really fits it but i don't think that it can be better than an iMac.
