We use the Blackberry for a corporate solution to provide wireless email and intranet services. We have a few minor problems with the service (lockups once a week, maybe). We are gradually expanding the applications and services available to our users. We have total control over what goes on the units and how they are used on the network.In comparison to Microsoft Pocket PC solutions.Pocket PC lockups 2-3 time a dayPocket PC data services and units are expensive and fragile.Pocket PC Users can and do load non business applications making support a nightmare.Getting corporate support for Pocket PC is like getting blood from stone and then you pay through the nose for it.Building apps for Pocket PC that work as a corporate solution for a wireless network over GPRS is buggy and unreliable.If you want a corporate solution that minimises costs and provides all the cost details up front, including support, use a blackberry.It is the easiest hand held I have seen so far.I can show most people how to use the Blackberry in twenty seconds.I have found Blackberry support very good incomparison to the Indian based support centre for HP Pocket PC. It will take me a matter of 1-2 hours to get a resolve from Blackberry.With the support for Pocket PC, I might, if I am lucky, find a resolve through the support centres that we have to use for Pocket PC (after many days of frustrating, broken english conversations). I hate paying for negative results.Building apps for Blackberry is well documented and have not had in problem so far.If you want to play games use a Pocket PC.The bottom line needs productivity, not wasting time.
