In all of history there have only been a few iPhone class disruptors. They are rare, and they come based more on timing and the presence of enabling technologies than any particular company simply investing billions in R&D.
Although I do wish Apple would buy some AAA game studios and make some AAA-quality games for their platforms..
Sony just announced their quarterly numbers. The PS4 just crossed the 100 million unit threshold over its entire lifetime. Apple sells that many phones in two quarters.
Stock buybacks were illegal until 1982, being considered a form of stock manipulation. Even though it's legal now, it's still one of the best forms of stock manipulation.
A company buying its own stock at market price is a wash. The reduction in the value of the company and the increase in the value of each remaining share balance out.
Almost by definition, there won’t be a larger market than one that already has 80%* market penetration among adults worldwide.
Also this BS about stock buybacks and dividends to become cash neutral is stupid. They should be betting on moonshot things that will be the next iPhone instead of all of this financial engineering.
