The filing of a patent for an all-glass MacBook Pro with potential touchscreen features indicates Apple's ongoing commitment to innovation in its product line. This move could excite investors and consumers alike, potentially leading to a positive short-term impact on Apple's stock price. The mention of exploring touchscreens for MacBook computers and foldable screens further underscores Apple's focus on leading the tech industry in innovative display technologies. However, as the product is still in the patent stage, the actual impact on the stock will depend on further developments and market reception.
