It *looks* great but I am really debating with myself as to whether I should take the plunge. My macbook is 3 years old but like new, upgraded to 16G memory and 1T harddrive (my HD failed one month before my extended warranty ran out, replaced, so it's new) ...so despite my desire for a new machine, overall I don't think it's worth it ...especially with the lack of USB (which I use frequently). Thinner and lighter just don't push me over the edge.
