see when I bought my 17" Toshiba laptop the people were saying that people don't buy it just cause its heavy... really portability is not an issue with this laptop. I through it in my backpack with the rest of my books and its fine. Battery life is only a little over an hour and a half or so though. But I don't have an issues with how "heavy" it is nor its size.
Hence I still don't like those really small laptops.
