Myself being a more mature Windows Mobile user, I find that the platform already has what I'm looking for in the first place.
- Web browser
- Email, calendar, contacts
- Music/video player
- Photo viewer
- Full fidelity MS Office document create/editing
- Remote access software in Remote desktop and Citrix Receiver
- Glance-able information on the home screen
Personally I see most mobile users as newbies still trying to figure out where mobile devices fit in their day to day lives. I've been using Windows Mobile since it was called Pocket PC. I've seem almost all my needs eventually meet in todays mobile offerings. Android is there, IOS is there and Windows Mobile is there. Now app developers just need to refine things, make them simpler, integrate into the cloud better and start making desktop style content creation apps. As far as I see it, there's not much that is left to do besides making that mobile device in your pocket the one device you use for everything. That's where I see Continuum being a huge leap into the future if it's ever widely adopted. Content creation is the next big hurdle to overcome with mobile. Continuum will help greatly in giving the user a work space with enough room to manipulate their content. Hopefully the processing power is there. Who knows maybe we'll find that more complex and processor intensive tasks like video editing, music and podcast creation/editing, layered image creation (like Photoshop) is good enough on Window Mobile with Continuum. But if the processing power isn't there, then app developers aren't going to bother. If Windows Mobile developers don't make the content creation apps then Windows Mobile will be just like every other mobile platform and will probably stay number 3 or just kind of disappear.
Windows Mobile still does have a chance to become the Mobile OS of choice for the business though, so that's always a possibility. Maybe that's where it will grow and gain some following.
