Hi, this is my first post here, so sorry if its in the wrong place.

Basic story is that I'm looking for a laptop to take to university with me in December. I'm planning on studying Maths with Economics, so I won't be relying on the laptop for too much 'specialist' programmes.

The main functions I want it to have really is to be quick, be able to handle multiple programs and webpages open at once, and I'll also be using it for Skype-ing home and for (light) TV and film viewing. I very much doubt there'll be any gaming.

I would like a 15-15.6" screen, and preferably a numeric pad on the keyboard - obviously this is just a preferance that I will forgo if I have to.

I DON'T want a HP or a Samsung. I've had bad experience with Samsung, and I strongly dislike the touchpad mouse on the HPs that are in my budget - in my opinion the roughness is vile.

The aforementioned budget is absolute maximum £500. Realistically, I love to only spend around £400.

I've been looking around, and I'm really not sure about what exactly I'm supposed to be looking for. Is an Intel I5 processor really worth an extra £100ish than an I3 considering my rather basic needs?

I'm going to include some links of laptops I've looked at, but other suggestions are welcome! Thanks in advance for any advice, and sorry for the long (and probably very boring) post.

This one also looks good, but lacks the numeric keypad, and I haven't seen this in the flesh.. http://www.dell.com/uk/p/inspiron-15-intel-n5050/pd.aspx?c=uk&cs=ukdhs1&l=en&s=dhs&~ck=mn 2nd generation Intel® Core™ i5-2450M processor (2.50 GHz, 3M cache) with Turbo Boost 2.0 up to 3.10.

So any help would be great - really feel as though I'm banging my head against a wall trying to find something!
