"More easily frozen?" ... Only if left outside
In this case size doesn't matter! Vaio is a good laptop line. Because of the thinner body they are more readily cracked (as in oops what did I sit on?)or (it doesn't fly across the room like my frisbee). The only complaint I have heard of is the screen part tends to warp. Whatever you do,
never everbuy a Compaq ... I have fixed too many! IBM surprisingly has a nice range of reasonably priced laptops, worth a look.
