i did my best to translate the dutch site.
I've got a few questions about these HP notebooks.

is that 450 euro worth it for 1.4 inch bigger screen size, a tv-tuner, a remote controller, and a bigger hdd capacity?
these have the same cpu, Gpu.

Can you help me out finding the best choice? i think that hdx18 is full hd and that dv 7 has a max resolution of 1440 i think.

thanks for your comments! wich one should i pick?

I think both have 9600MGTs are DDR3,correct me if i'm wrong.
And about comparison as u talked about the difference well the difference isnt worth 450 euro IMO,about 100-200 euros would be a better choice.
