▲ ▼ Practical handoff between multiple platforms
I use mobile and desktop devices on multiple ecosystems, and I'm sure many use even more devices than I do, across an even greater number of dissimilar platforms in a modern world that is increasingly fragmented on those lines and where interoperability is frequently commoditised by the likes of Apple. Platform-agnostic solutions enabling convenient handoff (e.g. links, images) between devices on different platforms, in a way suited to each platform, is desperately needed. Also desirable would be configurability of rules, allowing for items to be handed off to other devices with processing rules on the terminus device.
Almost every browser offer hand-off feature now i.e. ability to access tabs from other devices, for what else else do you think a hand-off feature is useful but not available?
