Criticism

As with Portable models from other manufacturers, restricted to the heavy weight portability clearly one, so there was little advantage to other Macintosh models, especially as the old dice -based Macs ( Macintosh Plus, Macintosh SE, Macintosh Classic) were quite easy to carry. At the same time, the high price was very daunting, the comparable fast and barely heavier, built at the same time Mac Classic, cost only one-third.
