What types of good laptops are good for this description?

I really want a good laptop with these features, thin, light weight, touch screen, 1080p hd led display, very good graphics card, i7 quad-core processor, 16" display, 1080p webcam, built in microphone and I also want a good keyboard which doesn't have spaces in between kind of like the MacBooks keyboard where the gaps are covered. The price limit should be up to £1500.
