Hi!
The brands I would buy are Acer, Asus, Dell, Lenovo and Toshiba (perhaps I'm missing someones).
If you are not planning using for gaming, just go for a non dedicated gpu, only with Intel HD graphics, which are great for browsing and video, also less battery consumption.
I would try to get a 6th core Ix processors (the ones which starts with iX 6XXX) and get at least 8GB of ram.
Regards
