That attitude is exactly the problem. Thinking "oh we'll just buy company X and check the [x] mobile/tablet box and we'll be in the game". The existing leadership probably smarted from that price tag and expected immediate results without years of investments like Google at least did. The CEO change also didn't help apparently.
I'd say this attitude is more common than many realize. Some seem to think "being in the game" is the thing. It's not just acquisitions - it's half assed investment in product lines. You have to win.
