all his innovations have gone about things the wrong way from my viewpoint, so while he's notable he's also subject to criticism
Apple's computers have always been overpriced and heavily simplified (with less functionality) compared to machines running Windows.
The iPod was a big step and so was iTunes, but they've also chosen to sell low bitrate music and refuse to allow FLAC as even an option. at one point, the music was even stuck with DRM.
those are pretty large missteps in my mind. I take any criticism he doles out with salt added.
