RIM's market share is shrinking fast. Stocks value also crashing and many are rumours about competitors bidding to buyout RIM. That is really surprising because at least 6 months ago some analysts still said RIM had a solid position and a strong presence into enterprise consumers. And still has it. But the question seems to be: for how long?In the beginning smartphones where... Some time ago there was no big reason for common people to have a smartphone. There was only two proposals smartphones had and they where a super cool convergence of multimedia, camera and GPS, the case of Nokia N95, and the productivity phones that evolved from PDA's.Blackberry, Nokia, and also Palm had phones with this second proposal. And productivity was their greatest appeal with that class of higly productive people that needed smartphones before everybody else in pre-iPhone era.Yes. The iPhone changed this. But not the iPhone itself but Apple's App Store. Which started becoming relevant in 2008 with the introduction of iPhone 3G. That is when Blackberry's chain of value for enterprises lost its dominance.While Blackberry had the best messaging system, with the best mailing and BBM (and still are the best on it), and the best data security, Blackberry was not a OS developed to be a ecosystem like the iPhone was. While the iPhone is the easiest and most profitable environment for developers RIM's ecosystem had limitations like this:Various screen sizes/densities and button layoutsData connection. Yes, making a data connection is not trivial on BlackBerry.OS support. Currently, for example, foursquare supports OS 4.2.1 (OS running on 4 year old devices) and up. Something doesn't happens on RIM.Application distribution and updating. Foursquare currently makes 3 different builds to satisfy varying OS functionality and API features. Some companies go as far as making up to 7 or 8 separate build, one for almost every OS level. Licensing for putting your app in RIM's appstore even costs the developer the amount of 200 Euros Those and other reasons unknown by me (I'm not a developer) made the iPhone a much more developer friendly platform. Even the iOS experience itself is somehow influences the user to buy apps impulsively. And still talking about productivity, even without the physical QWERTY keyboard, the iPhone's touchscreen offers faster navigation's through menus for the user, with the bonus of being more intuitive. Those elements together impacted on Blackberry's greatest appeal: productivityWhile Blackberry still has the best and safest messaging, with physical keyboard, the iPhone made itself more productive by offering a big pack of highly productive apps and services. Services and apps developed for particular business areas like nutrition, pharmacy, law etc... Things the Blackberry couldn't have. Which even Android has more developed then Blackberry.The last and most impacting and cruel features Apple brought where a highly safe environment, not as safe as Blackberry's cryptography private Internet but an environment most developers concerned with safety say you can trust blindly. The messaging services like Whatsapp, Kik and others which where available for the iPhone since a long time. And now the iCloud, who promises
