Provide work correction / word completion software
Touch-screen input on the 5800XM is substantially less effective than on the iPhone / iPod Touch (I own both) for one simple reason: the iPhone has word completion / word correction software. Why does Nokia not have this feature available? Please add it or work with a vendor (e.g. Adaptxt) to make it available for S60 5th Edition.
Note that HTC Hero running Android will also have this feature. it's all about increasing productivity.
