I'll admit that calling an app window an "activity card" felt a bit foreign. That said, however, I loved the ability to group related items together, regardless of which app they were in. The idea of gathering, say, a PDF with a related document, a map, and a Web page is a terrific rethinking of what "multitasking" can mean in practical use. I hope that Apple and Google figure out how to integrate a similar concept into their respective operating systems--in iOS and Android, related app content is siloed, not as manageable as in WebOS.

C'mon, it's a Web-connected world: It would be nice if the now-defunct WebOS weren't the only mobile operating system to truly exist in concert with other mobile services. The ability to unify contact information--and even access images stored on Facebook directly from the tablet--were nice add-ons that made the WebOS-based TouchPad feel more connected than its Android and iOS competitors do. The Web is one big sandbox, and everyone needs to play nicely there. The better the integration, the better users can maximize their presence across the Internet. Keeping information isolated runs counter to a connected world; the level of service integration that WebOS and the TouchPad had was a differentiator, and it's something that Apple and Google should, again, look at closely.
