Maybe Apple is onto something with the introduction of the New Macbook line of notebooks. If Apple continues the successful line of MacBook Pro notebooks with the "older" features, (ODD, hard disk drive, ethernet connectivity), and add to its product line a futuristic New MacBook series with "modern" features, (retina display, SSD storage, WiFi only), then they create an ability to cover many price points while maintaining strong sales of their current notebook lineup. This strategy may protect the interruption of strong sales of the 13 and 15 inch models that are currently in place while allowing for a methodical shift to the future product lines. This is a defensive strategy but would allow Apple to introduce a new product line, (new Apple products always seem to create a buzz in the Apple community which results in high sales volume), while maintaining strong sales of historically successful products. New Apple users may be created with the new lineup as they tap into existing markets by creating new price points without having the appearance of cheapening their products. Whatever Apple does...quarterly sales growth will more than likely continue a constant upward trend.
