What laptop to get for high end budget??? (2014)

Hello everyone,

I am starting mechanical engineering in university next year and I would like to buy a decent laptop this summer before I start. I do programming as a hobby and I will be using some memory intensive CAD software and some programming IDEs. I am planning to do partition with Ubuntu and Windows 8.1 (so no mac). I don't do gaming but may start if I get a good gpu in my laptop.
The properties I am looking for is:
- Full HD or higher display (preferably IPS, truecolour and all that good stuff)
- 8gb or higher ram
- 256gb or higher ssd (i really don't like hybrids but may compromise and not even mentioning hdds)
- 14 inches or higher screen size (definetely not lower, i used a 13.3" and it was the worst thing happened to me)
- 4th gen i5 or i7
- much preferably thin and light form factor(definetely not those huge gaming laptops they make)

What I found is all these properties usually comes with 13.3 inch laptops which is really too small. I would have built my own pc but I need a laptop to carry around to lectures and library. I looked everywhere and I mean everywhere, but could not find a decent laptop that ticks all these boxes. I can go up to £1500 or maybe higher, but cheaper laptop would be nice. I know I am quite picky, but can you think of any laptop that ticks all the boxes?

I would really appreciate any suggestions!
Many thanks in advance.
