Samsung is mostly a hardware company, sure they have some software.
Microsoft is mostly a software company, sure they have some hardware.

But there comes Apple. Apple is both a hardware and software company.

Yes, Microsoft and Apple both helped each other in the early years. But what platform was Microsoft Word, Excel on first? Apple products, example Mac OS and hardware. Why didn't Microsoft build Word, Excel for their operating system first? I haven't figured that out yet, except for maybe the fact Apple's hardware is able to do handle the processes of MS Word/Excel. Whereas the hardware the MS OS was on, which we all know aren't MS to begin with. Especially back in the early 90's when MS Word/Excel came out.

Now it's 2015, and MS yet again made another retention of MS Office specially for Apple's iPad Pro. Why? Because of hardware. Again, MS doesn't have much of an hardware and it has failed on trying to enter the smartphone business.
