Hello. I am currently looking for a new laptop to upgrade from my previous one. Right now I have a Acer aspire E15(i3 6006u, 8gb ram, 1tb hard drive) and I just don't like it. It has terrible build quality, bad battery life and it is extremely heavy. I am doing a computer science course in college and while working I usually have a lot of applications open (multiple tabs on Firefox, visual studio, Microsoft word ect). The Acer I have at the moment is very slugish even handling applications like these and I have to take a charger with me which takes up loads of space in my bag. So my question is, what would be the best laptop(for under £800) that is light and has a great build quality and a long lasting battery life. A friend has a hp omen and he says the battery life is great but online it says on average 5-6 hours and it also looks like it would be heavy. I know I could probably go cheaper than £800 for what I do, but I want something that can keep up for a couple of years.
