And here are some of my favorite candidate widgets for the device. PC versions of all of these have been already talked about over the SDN :
1) Alerts : One Widget to bring them all.... - This widget would be used by a normal employee for monitoring all kinds of alerts from business workflows and various other sources.
2) SAP News Mashup Widget - This will always keep you aware of the latest updates in the SAP ecosystem.
3) How to configure and use the xMII Generic Widget - xMII stands for xApp Manufacturing Integration and Intelligence ( I also learned this recently through SDN). This would definitely be of great value for the tough guys running big manufacturing plants.
4)Yahoo Widget for BI Data - This widget would be used by managers and will provide them valueable insight about their organization.
