the one on amazon is better then the one that was on newegg anyways.. so if the prices arent drasticly different then go with the one thats on amazon..
btw asus is full of c**p anyways.. the x1 is the model identifier for the variation difference in the series and has nothing to do with newegg..
take notice that the one on amazon is N61Vg-A2 and the one on newegg uses X1 at the end.. basicly its there for asus tech support to know what hardware is on what laptop without actually having to start it up and find out..
