I believe you may be overstating your point, or maybe it's the wording, but I hope you are not implying that sony or hp or samsung, with almost 200 years of total company histories, have not invented much and have survived by sheer luck.
I believe Sony has some significant innovations in portable music players back in the 1970s, and certainly made major strides in transistor radios in decades prior. Samsung I'm not really aware of any innovations from, but I wouldn't deny that they may be there. HP was very innovative in test equipment, but not so much in personal computers, as far as I am aware.
But it is worth noting that I was genuinely asking a question. It is easy for me to think of the innovations I named (and many more) from Apple, and the ones I named from Google, but off the top of my head, in the areas of mobile phones, tablets and personal computers I can't think of any from those other companies... and wondered if I wasn't missing them... so, by all means, if you have some significant innovations to bring up, I'd be happy to hear them.
