U310 or U400?

Hi, this is my first post, my name is Intel-4004. I need some help choosing laptop for college...

I went to their website and saw the price for a U310 and the U400 is the same.

U400's spec:

They both has something that I like.
the U400:
- Larger screen
- have dvd/cd drive (have no idea, but feel better having it)
- it has Core i5(good) and Radeon HD 6470M (can play games )
what I don't like
- seems thick and heavy to carry around...
- I heard people say its battery is not very good
- Amazon reviews

the U310:
- light and thin
- longer battery life than the U400?
what I don't like
- maybe too small?
- HD 3000...(how much games I can play on it?)

So which one should I get?

 

Not too much if you'd like to set something higer then min details (or even play at all). And that would be bigger disadvantage in this model.
I wouldn't call it thick but rather more classic.

I'd like to buy something 13-14" for my self and if i had to choose from those two I would get U400 because of graphic card.

Try to find something with HD4000 which is much better card. And maybe with nVidia Optimus technology if with dedicated card because this will get more hours from battery.
(I can't help you now because it's almost 1:30AM here and I have to get to work in few hours )

 

Thats what I'm thinking, but the other ideapads are too thick...any suggestions? even from other brands or series? but similar price?

 

Hm...I tried to find something but all I get was only few notebooks with your criteria and one of them was U400 . The others are:
Samsung Series5 - I would prefer this one because of matte display, good graphic card and it's a little thinner.

Packard Bell EasyNote NX69HR
Sony VAIO SVE14A1V1E
sorry for language but I don't have time to look on english websites

 

...ok...oh! I found this yesterday. The Thinkpad Edge E430
spec:

Spoiler

Intel Core i5-3210M Processor (3M Cache, up to 3.10 GHz)
Genuine Windows 7 Home Premium (64 bit)
14.0" W HD (1366 x 768 ) LED VibrantView, Midnight Black

6 cell Li-Ion Battery 48WH - 75+

Intel Centrino Wireless-N 2230 (2x2 BGN & BT4)

It doesn't clearly state the graphic processor is HD 4000...I didn't look into it since it seems too thick...do you think this will get me through college without dropping too much performances?

I'm not sure why,but there is not much video reviews about the Edge series...

 

The u310 is ivy with hd4000

 

Ya, but they are out of my budget...I'm looking around $500-$700
