Windows Mobile is dead. Windows 7 is called Windows Phone, because most has been rewritten. As a result, compaibility was broken. Still a young OS (hence the rewrite reference), it has a few things missing or disabled, because MS chose to disable them rather than having them buggy. Multitasking, for example, is disabled until it's smoothed out and has been announced to make a comeback soon. Some have speculated that having WP7 will mean no copy paste, no multitasking, etc. While technically correct now, MS has announced the features and promised to release them in smaller updates, before yearly updates roll. So, WP7 will be getting some of its features sooner rather than later. I assume that's what he means.
