If you want something more stylish an imac might fit that criteria slightly better which is arguably about as portable as this. IMO the HP is better suited for lan parties, but not for carrying around on a daily basis. The 7kg seriously is a bit too much for it to be truly portable.

The keyboard itself looks really uncomfortable, from my past experience of using of desktop replacement, and kinda unsuitable for prolonged gaming and daily use (although this is just based on the looks of the machine). Also it's arguable that the graphics card is somewhat underpowered for the resolution (wsxga: 1600x1024 do any new widescreen games support this resolution natively anyway?) since you can now get laptops with 8700gt mobility chips these days.
