For designing apps to run on tablets, the user interface model of tabs is out, replaced by filters , says Sean Whiteley, vice-president of marketing at Salesforce.com.
The company just formally announced the Series 5 and it turns out it's going to be joined by the next-gen Series 7 Slate as well. (Also known as the ATIV tabs in regions outside the US.) The two 11-inch tablets more or less look alike, except the Series 5 is powered by an Atom-based Clover Trail processor, while the Series 7 packs Core i5 guts.
And he adds that there is ongoing substitution of tablets for PCs, while Microsoft and its partners are not up to scale on Win 8-based tabs and hybrids.
