It is been approximately more than a month ago when on SAPphirenow (14-16 May 2013) also SAP Fiori was announced. SAP Fiori is a collection of apps with a simple and easy to use experience for broadly and frequently used SAP software functions that work seamlessly across different devices (desktop, tablet, or mobile). The Fiori is considered as “Consumer grade UI”. Meaning a new, modern and design thinking driven user interface (UI). Fiori currently has 25 apps which cover frequently used functionality with SAP software, e.g. create sales orders, entering time to timesheets, approve requests, etc.
Fiori targets to cover 80 percent of SAP users and 45 percent of SAP system functionalities usage. From technical perspective Fiori is based on SAP UI5 (also introduced quite recently). SAPUI5 is then based on HTML5 based standards. Fiori is optimized for the Google Chrome web browser. Fiori’s back end connectivity is provided by SAP’s oData (Open Data Protocol). Backend functionality is exposed by Gateway (NetWeaver Gateway (formerly called "Project Gateway)) services. Most likely Fiori apps can be ported to any version of ECC 6. Notice that Fiori doesn’t require Sybase Mobile platform called Sybase Unwired Platform (toolkit formally known as SUP).
The pricing of the Fiori? Seems only $150 per user for those above mentioned 25 apps.

PS: Curios about the name? Actually Fiori means "flowers" in Italian.
