Engineering laptop

So I need a good computer for my Nanoengineering course and I'm not to sure about what would be the best deal. my price range is about $1000-$1400.

I was looking at making a customized Sony Vaio:

Intel® Core™ Quad i7-740QM processor (1.73GHz)

Microsoft Windows® 7 Professional

Black

4GB (2GBx2) DDR3-SDRAM-1333

320 GB SATA Hard Disk Drive [7200 rpm]

DVD +/- R DL / DVD +/- RW / DVD-RAM Drive

16.4" VAIO Premium Display (1920x1080) Full HD

NVIDIA® GeForce® 330M GPU (1GB VRAM)

Keyboard Backlight

Large Capacity Battery

So i have a 2Tb external drive so i dont need extra memory. The reason i'm asking is because i've never owned a laptop, even for that matter a laptop, and there has been a lot of hate for Sony so..... any help would be appreciated
 
Memory and storage capacity are two entirely different things, but I agree you have plenty of both (4GB RAM, 2+TB storage).
Engineering is about crunching numbers, and even the most basic laptop will do that very well, so we need to know what software you'll be using, especially any auto-cad type programs.
I'm not a Sony fan either.
