I have to add one more observation, because IMHO lots of people who recommend some manufacturer are wrong. Lots of manufacturers have different classes of products divided based on quality, price, features etc.
Lets take Dell as an example. This manufacturer has some classes for home users (low cost Inspiron, high end XPS, Alienware for gaming, etc). Other classes are addressed for business customers (low cost Vostro for small office, high end Latitude, high performance Precision, etc).
We have similarities in other manufacturers. HP's Pavilion and Envy for home customers and it's ProBook and EliteBook for business. Lenovo's IdeaPad and low cost ThinkPads for home users and highend ThinkPads "X" and "T" series for business. I do not have much experience with other manufacturers, but I am sure it will be the same.
If you choose some high end computer from whatever manufacturer, I am sure that you can be satisfated. Personally I don't like HP much, but I saw perfect EliteBooks I cannot say anything bad about it. Lenovo the same. So when I want to buy laptop I do not looking for some specific manufacturer only - I am choosing from offer of high end laptops from various manufacturers and choose some with fits my needs.
