Admittedly, I haven't read up a ton on continuity, but I'm not seeing the huge appeal. I can accomplish the same thing with Dropbox, can I not? I heard one person say "but if you're working on a spreadsheet on your laptop and then walk away, your phone will automatically pop up with that same spreadsheet!" That seems like it would be a pain in the a** after a while, personally. Usually, if I'm walking away from my laptop, it's not because I intend to keep doing the same thing on my phone.
Never mind the fact that a *very* small percentage of users (even iPhone users, according to the numbers given at WWDC) are actually using a Mac OS. And that was the only new feature I saw from WWDC that wasn't just playing catch up.
Cook beamed with pride during the keynote, pointing out that they had had a lot of new iOS users switch from Android, but failed to mention that it was largely because they had entered new markets last year. "Stealing" a couple of percentage points from your competitors in a market that you just broke into isn't surprising. It should be expected.
I keep pointing out, too, the comments Cook made about Android. When your marketing focus changes from bragging about how good your product is to talking about how bad your competition is, it means you've got a problem with your product and you know it. Whenever companies start mud-raking their competitors, IMO, it shows that they are terrified of those competitors. Especially when that mud-raking is filled with half-truths.
