The purpose of this topic is to discuss the various strategies of the various smartphone manufacturers, as I keep debating with myself which of their strategies are best. For the purpose of this topic, lets consider these 5 smartphone OSs: iPhone OS, Android, WebOS, Blackberry and Windows Mobile. iPhone OS: Now I might be biased towards the iPhone OS because I have an iPhone, FYI. Anyways, I think the iPhone and the iPhone OS are pretty polished products. From a touchscreen device point of view, there really isn't a whole lot of stuff they can add to the iPhone hardware to make it better, and the OS is great, and hopefully iPhone 4.0 will finally bring some sort of backgrounding and notification management. And of course, the App Store is great, having sold nearly 1.8 Billion Apps. A problem I see with the iPhone OS domain is that there isn't a phone for everyone. Not everyone wants a touchscreen keyboard. Having only one device on one network (at least in the US) isn't helping apple, but maybe thats the game they want to play. Android: I like the idea of Android, I just don't know how well it is going to end up. Theres just something I don't like about the set-up... if something is wrong with the phone is it the carriers fault, the harware manufacturer's fault or Google's fault because it's their OS? (the word "fault" is used for lack of a better word) If Google really tries to push Android to the business side, I believe they can eventually take a large chunk out of WinMo's market share, since Android will be deployed by many different cell phone manufacturers, much like WinMo. WebOS: I think Palm has done a great job with the Pre and WebOS, and now the up-and-coming Pixi. They've put themselves in a good position to (eventually) have multiple phone options on multiple carriers, but why did they decide to have another Sprint-exclusive WebOS phone? I love the multitasking and notifications setup in WebOS, and wish Apple would get a clue. WebOS has a slider, a non-moving keyboard, and I'm sure it's only a matter of time before they have a horizontal slider and a fully touchscreen device, giving consumers many options. Blackberry: A variety of Phones on every network. Exactly what I think Palm is going to shoot for (except with more innovation), and exactly what I wish Apple would do, but won't happen. Blackberries are great phones for email and other business "stuff". They need to work on App World and Web Browsing and some other stuff, but I think they're doing good. They need to innovate though, because Palm is looking to take their spot (eventually) WinMo: Windows mobile had a head start in the smart phone business, which is why there are still so many WinMo phones out there. But Microsoft has been standing still and has been passed up by almost everyone in terms of innovation and ease of use. But I guess we'll see if this changes with 6.5 or WinMo 7. Anyways, this has been my take, what are your thoughts on the major players in the smartphone industry?
