Does it really matter what you are using in order to complete your task - well it may be.....! having keyboard of different company doesn't make any huge difference because typing is just about to same on each and every device rather its smaller on smartphone and bigger on tabs or general, but the arrangement of character on QWERTY keyboard designed by Christopher Sholes, the inventor of the typewriter wont be change or we can say keys are pretty much same in all.
