Bloomberg Businessweek drove that point home on Tuesday, profiling major firms like SAP and Mercedes-Benz that were, sometimes tentatively, beginning to deploy the iPad out on their front lines:

[Rob Enslin, North America president at SAP] says that when he travels, the only device he carries besides a Research In Motion (RIMM) BlackBerry is the iPad. “It’s allowed me to almost run a paperless office,” says Enslin, who uses it to access business applications, briefing documents, customer information, and other data.

SAP, based in Walldorf, Germany, also works with clients to put its products on mobile devices including the iPad. Tellabs, for instance, collaborated with SAP and Sybase on an iPad application that lets managers more quickly approve shipping of customer orders. “We also have three or four different applications lined up behind this that will help us with better inventory control,” says Jean Holley, chief information officer at Tellabs, based in Naperville, Ill.

It’s not surprising given the iPhone’s success with everyone from executives to delivery drivers, and while some still question the iPhone’s enterprise readiness, the activity in our very own forums indicates many companies are still forging straight ahead.

But will it even matter to the enterprise? Windows Mobile devices have long been a consumer also-ran, but have found die-hard users for specialized applications in areas from the warehouse to the road to extreme heat and cold situations. They often put the “computing” in mobile computing, but it doesn’t look like Microsoft is trying to keep that market with the latest update, which Ed Hardy dubbed the “Zune Phone.” It probably makes a lot of sense from Microsoft’s perspective, but what will power enterprise warehouse floors now? Will device manufacturers rejoice at getting to drop the “Microsoft tax” and go with custom Android builds? Will Microsoft have a legacy program to keep this market just sated enough not to leave? Will we see Windows Mobile 6, like it’s distant (distant!) cousin XP, be end-of-lifed for years and years to come as demand continues and companies resist upgrades?.

I’d love to hear your thoughts, either in the comments or at Michael@ITKnowledgeExchange.com: Does Windows 7 Mobile matter to your business, and if so, how — even if it just means you need to start planning a transition to something else?.
