Prediction: Apple will probably quietly introduce SMB-focused changes in the next year to make it stupidly simple to create custom apps and distribute to iOS devices outside of the App Store, then everyone else will spend 3 years chasing that angle. :/
I know your point was enterprise IT, but allow me to illustrate with a consumer example. The same reasoning applies.
Here in India, I see most of the hip young crowd carrying Blackberrys. Note that unlocked, grey-market iPhones are available in India at not-too-deterring prices. But Blackberrys are defacto, and all you see people doing is message, message, message.
We have some of the rock bottom rates on calls and SMS - yet you can buy a fixed-rate Blackberry messenger subscription at nearly every service provider in India which lets you do unlimited group messaging (irrespective of domestic or international). I think you can also group-message a certain number of multimedia items.
Now that is something that not even Apple has cracked. The system is seamless.
<begin prediction consumer> The only competition to Blackberry in the hip-messaging market will come with the Facebook phone which will seamlessly integrate the mobile angle to the Facebook Messaging platform. </end prediction consumer>
<begin prediction enterprise> R.I.M can only be broken by the final integration of Google Voice, Gizmo5, Slide/Disco and some form of video chat into Android. The notification-bar on Android is simply custom built for messaging notifications. </end prediction enterprise>
If memory serves, before RIM moved in, Palm owned the enterprise handheld market. They could do it again if they tried.
If I were at Palm now or before their acquisition by HP, I would be pushing to ease up on the consumer focus and make an all-out attack on Blackberry's home turf.
RIM has completely lost focus. It has taken its eyes off of its own flagship product, and is busy trying to copy whatever anyone else is doing--but it can't really make up its mind who it wants to copy.
I think WebOS could have been a tremendous hit in enterprise IT departments. Anyone who can handle basic web technologies can write apps for it. If Palm had focused on the enterprise segment, WebOS could have been God's gift to any IT department saddled with a significant number of in-house applications.
Grab someone with a web development certificate from the junior college, give them a month, and you can have an app on all your in-the-field employees' mobile phones. Oh, and you can trivially port it to your desktop machines, too!
