The difference is that I was able to initiate the download of the admittedly awful iOS 7 on day 1 it was released, and it was downloaded and installed within 30-40 minutes or so on both iPad and iPhone. If I could at least
start the download process on my Nexus 7, no matter how
slow, and at least observe the
progress of the download, I'd say nothing at all. I would have expected Google to wield more server power than Apple, but I guess not.
By the way, if you call 17+ days "several days", that's a hefty understatement.
