Well if you want, you can always build a Laptop from scratch online. choosing what components you want (or don't want) in the computer.
A couple of my favorite online stores are...
1. I Buy Power. It is a great site to buy really good gaming computers for good prices.
- http://www.ibuypower.com/
2. New egg. Another great all around computer and electronic store.
- http://www.newegg.com/
