Ok iv narrowed it down to these two. I am looking for portability including battery life, and a relativly light weight for what I am geting. Battery life is a larger priority. The m505 has the 9600, but is limited to the 1.5 pentium M, where with the x1000 i can get 1.7. What are your opinions on these computers? Build quality is also an important factor. They age going to be going to college with me.
