I think i won't need a new laptop in at least 4 years

I bought this laptop because I needed a new one, but with great perfomance, mainly for high demanding games, high demanding programs like image editing, 3D modelling and rendering, and Video editing and converting. And it has me satisfied. 

Pros: 
The greatest thing in this laptop its their speakers, they are juest AWESOME, the best laptop speakers in the market.
The screen its great, its very shinny and the image is very sharp and vivid. 
The kerboard is good but its better with backlit, unfortunately the one I bought doesnt has it. 
At least mine, doesnt heats, even with very demanding programs and games (like GTA IV, or Rendering 3D, or Video Converting). 
Good Ports... USB 3.0 eSATA USB combo, display port, HDMI, two audio out, etc. 
Good quality image with the integrated camera. 
Cons: 
This new technology "Optimus" sucks, it does saves battery, but some programs and games didnt detected de discrete GPU (it has two, on integrated and the nVidia) at first (I needed to do some tweaks). 
Maybe one usb more could be useful. 
The charger its kinda big. 
Doesnt comes with the OS cd (you have to buy it from Dell).

Unit with all the accessories including the external DVD is a great buy

Dual core runs fasts(XP) Vista a little slow. Dual core CPU does run hot use a fan or cool pad to reduce the heat to acceptable levels. Needs a little more cooling capacity to increase longevity of the unit. Any air restriction can cause severe thermal issues. Bought a brand new keyboard under $20 installed in 5 minutes unit is used looks like new, A 12" screen netbook can't beat it. Very light easy to handle. Just keep it cool. A cool pad with fans keeps it under 50C on the CPU the hard drive is ok!
