Yes I too agree about the BL bearings and that they should be changed into ceramic, but what I am trying to understand though is why the Boca are superior in cost over the Acer? as I said befor, some people said that the Boca uses a pure ceramic bearings unlike most companies like Acer where they use what they refer to as hybrid ceramic balls which are steel balls with a somewhat thick cover of ceramic??!!!! I dont know.
