Types of 'Smart' mobile phone available on the market

Are you confused with so many types of 'smart' phones being addressed and available in the market. Here are some guide and explanation that you may find useful. But first of all, they are called 'smart' mobile phones because they have an OS (operating system) build upon them making them 'smarter' than normal non-OS based mobile phones. This OS extends their functionality from normal phones, and can be equivalent to mini mobile computers if you like them to be called (not wrong, right?).

1) Windows mobile (OS) based, no doubts this is one of the popular one available in many smart mobile phones found in the market. More appropriately, it should be called PDA-based phone because its 'PDA' function is usually more than its 'phone' function. Yes, this is the younger brother of our computer popular OS from Microsoft Windows. Its current version is Windows Mobile 6, anyway. Popular manufacturers are like HTC, HP, Asus and Samsung (just join in the race), etc.

2) Symbian (OS) based, the most popular one is Symbian S60 platform, mostly implemented by Nokia in its wide range of smartphones. Nokia is Symbian's strong supporter and sponsor of development. They just introduced their touchscreen version of S60 platform recently, so we can expect a bright future for this OS-based phones in future due to many well-received products. It can also be found in new range of Samsung smartphones and some Sony-Ericsson smartphones.

3) Linux (OS) based, less popular and can be found in a handful of mobile phones only. Few of them are from Motorola. This is the younger brother of its elder brother, open-source Linux for PC and servers.

4) PlamOS based, once very popular for their user-friendliness of PDAs and later smartphones. Most market share being taken by Windows Mobile, I assumed. Having its own brand of PDA and smartphones.

5) RIM Blackberry (OS) based, becoming more popular nowadays due to its easy-to-use operation, was originally designed for business use especially for heavy email usage. Recently it was integrated with considerably multimedia support.

6) iPhone OS from Apple inc., becomes popular since its first generation of iPhone. Multimedia-rich and user-friendliness is its selling point. Its second generation of iPhone was released out few months ago.

7) Google phone. This is a new born baby, just joining the range of 'smart' mobile phones, is based on an OS called 'Android' by Google. Its first phone is built by HTC, called T-Mobile G1. What will be its fate? Too new to comment, just wait and see.
