The problem is that Sharp works against itself. While the Sharp development team are trail blazers IMHO, the Sales and Marketing team (responsible for the US and European markets) are trend followers. When I think of them, inept comes to mind....
Sharp has consistantly misjudged the wants and needs of the US handheld market. You can go back to the orginal Sharp Zaurus SL-XXX series. It was an excellent unit with features way ahead of it's time, with a fanatical group of owners (much like us), with forums, webpages and support groups (because Sharp's support also sucked). SHARP chose to not share the SDK of that Zaurus and so no significant 3rd party software could be developed. As a result, sales of other palmtops and handhelds over took those of the Zaurus and it was discontinued. Although Sharp compensated for that early SKD mistake by introducing Linux based open sourced machines (which was a nice move), they again got it wrong by not selling the the C-XXX series here and in Europe. They got it in their head that the US market would not want clam shell units, I guess because of the popularity of the Palm Pilots a few years back. Another example is the Sharp Mobilon, which was just a knee jerk reaction to the budding Windows CE market. Sharp would have been much better served to continue developing the exsisting devices (The Sharp Zaurus SL-XXX being one) which was already established and brand recognizable, Lord knows they had the talent, but instead chose to discontinue the Zaurus and jump on the CE band wagon with a CE machine of their own.
So I recognize Sharp for what they are - Great at hardware and development and terrible at sales, support and marketing. If they would just listen to some of the great suggestions they have had over the years from owner and the likes of forums like this one, they would have got it right a long time ago, the development talent is there!
