Owning a Windows Mobile mobile, is like a torture. As an owner of a Samsung i600 (Known in the USA as AT&T Blackjack - Windows Mobile Standard 6.0 - no touchscreen) and of a Sharp WS003 (Windows Mobile Professional 5.0 - with touchscreen), i can easily affirm that both standard and professional devices are NOT optimized for real-life usage. Very long loading times, useless on-screen-keyboard (unless you have the precision of a neurological surgeon), and "broken" software (I mean: it is not polished and refined). This is mainly because Microsoft gives to manufacturers a "raw" operating system, and they have to add, polish and refine functionalities at their own expenses. Photo management? You do it by yourself. MMS? Do it. Wi-fi and Bluetooth stack? We give you a basic one, if you want you can enhance it by yourself. Accelerometer, GPS and so on? They will be invisible to the default system, you have to write your own drivers.
So, many manufacturers, has sold Microsoft "plain" operating system, like my old MiTAC Mio 8390, an awful mobile with a lot of bugs; while others, like Samsung, has splurged on third-party licences, to make look Windows Mobile more refined.
Nowadays, with the iPhone, Android and the very promising Palm Pre, the smartphone compatition is becoming very interesting, so Microsoft has finally decided to innovate his Windows Mobile, virtually unchanged since 1999.
