Is that really that big of a deal? Seems like one of those things that are NEAT but lose their appeal overtime, especially on such a small screen. Sort of like the page flip for ebooks. Seems awesome at first, but then you compare it to just tapping the bottom of the page and you start to forget how "awesome" that animation was.
To be fair, I've never actually seen live wallpaper. But I doubt the lack of it would turn me off of a phone that otherwise met or exceeded my needs.
Kind of reminds me of all the animations and effects that Ubuntu can do. They're fun at first when you show your friends what your FREE os can do, but except in showing off, how often do you continue using them in your day-to-day? I tried to make use of the cube spaces, but it was a mental requirement rather than an actual benefit to the experience.
