He missed one, IMHO: apps which can live on the springboard or the lock-screen. I'm not anticipating that Apple will do these, mind you, as it complicates their simple UI scheme, but it's a clear advantage for Android power-users. I'm hoping that they plan on making a big push on cross-app communication. I also hope that they're investing in their platform from an e-commerce perspective: paid upgrades, trials, video…
A million times no. The Android homescreen is incomprehensible to me as an iOS user and the main reason is the clutter and weird alignment.
Honestly, the biggest reason I want it is for things that apps aren't allowed to access anyway: a global control on the Springboard to disable WiFi, or change screen brightness, for instance.
