Looks like offline Gmail on the iPhone wasn't the only trick Google's Vic Gondotra has up his sleeve during his talk at MWC -- he also gave a quick demo of Google Maps running as a web app on the Palm Pre. Of course, what's interesting there is that the Pre's HTML-based SDK means that web apps can act like first class citizens on the device -- which is probably why Vic called the Pre "arguably one of my favorite devices." Hopefully that means we're going to see a lot more Pre devs really blur the line between local and cloud-based applications, but for now we'll just settle for the short demo video after the break.
