And thus the insanely smooth user experience on iOS. As an Android developer, this is _the one thing_ I feel makes it difficult to have a polished user experience on Android compared to iOS. Yet for WP7 its also silky smooth. The main issue on WP7 for user apps isn't GC at all, but rather the network (creating long lists of images that you're getting from a web service). Once people learned some techniques for dealing with that on the device the experience for 3rd party apps was just as silky as iOS apps -- yet a full generational GC. The GC is an excuse (unless its not well written), not the reason.
