How much you want to spend is always an important question when looking at laptops that are "best for you."
I found 2 suggestions, at 2 different price ranges, that I think will fit well.
The first is the Acer Aspire 7552 at $799. It has your 17.3 in screen, 4 GB RAM, and 500 GB hard drive. Great computer. Here's the link http://www.microsoft.com/windows/pc-scout/laptop-details.aspx?pcid=28c18ecc-d519-e011-89fb-02bf9d3bf32a
Next, for more pricey range, there is the Sony VAIO F at $1,119. It comes with the sweet i7 core processor, which is a beast, and 4GB RAM, and 500 hard drive. It even has Blu-Ray R for added benefit, which is really nice. Here's the link - http://www.microsoft.com/windows/pc-scout/laptop-details.aspx?pcid=1e070925-a007-df11-927f-02bf9d3bf32a
Like I said, its all about what you're gonna do with the laptop, and how much you want to spend. I think this is a good start. Let me know what you think.
