Which laptop should i get?

I've narrowed it down to 2 choices. Both are around 15". Need it to fit into my laptop-bag-that-doesn't-look-like-a-laptop-bag you see. So only going to look at 15" laptops.


Sony Vaio (VGN-NW ISO J/T) in walnut brown. I'm really attracted to the wood feel. hahhaha! Cheap with a 4G ram. However, graphic card is not very good. Well i can always customise the graphic card to suit my needs right. Other than that, its a rather good laptop. Am really attracted to the wood. hahaha!

DELL Studio 15 in black
Very good performance laptop. Would be much easier for me to get since dad deals with Dell. A little bit more expensive than the Vaio though. Seems like its a very good laptop, from the online reviews.

Well, now, all i want is a laptop that doesnt easily hang or lag. Thats the main purpose.
