Bbelieve it or not the Dell 700m is heavier than the D610. I think that is what I will go with, has a std. 3 year warantee on it. Coming from an Ex-Bestbuy Computer salesman, most of the stuff that goes wrong happens in the first year, but having that extra protection is a comfort thing. The D610 can also have a dedicated video card on it, and the higher res. screen. Thanks everyone!
