What will you be using your laptop for? The Sony Vaio NW series is a great multi-purpose laptop. It doesn't have the most powerful processor available, but should be adequate for most tasks (besides video editing and powerful gaming). It has 4 GB RAM and 500 GB hard drive space. It is also a great size (15.5" and 5.3 lbs) for a beginning laptop user.
