While I don’t expect everyone to be as device-crazy as I am, one of the obvious consequences of convergence (the idea that more gadgets will become more computer-like — think smartphones, tablets, etc.) is that more people will have more devices. This creates new problems for users who, especially if they are from the US, were previously used to accessing their services/information mainly from a single device. After all, a well-built service or source of information should optimize experience around the user, not which device.
This proliferation is one reason I think internet services like Evernote and Gmail took off: for someone working with multiple devices, its much easier to make sure every device has access to the same data and functionality when the data and functionality aren’t on the devices themselves but hosted somewhere “in the cloud.” (Thank you, Dilbert)
The same logic applies to syncing services like Dropbox and applications like Netflix and smart syncing software like Chrome: they make it easy to ignore which device you’re using and just focus on the functionality and data that you want access to (in the case of Dropbox, its files; in the case of Netflix, its your viewing history and your place in a given video; and in the case of Chrome, its browser history and preferences).
Its gotten to the point where there are enough app developers and technologists working on this type of syncing that I get disappointed when a service or application fails to intelligently think about syncing as a way to delight the user. For instance, I get regularly irritated by the Twitter app for not tracking which interactions (@replies, favorites, re-tweets) I have previously seen. As I routinely move from one device (a smartphone) to another (a PC) to yet another (a tablet), with each device, I need to recheck which tweets and interactions I have seen and which I haven’t. While this is hardly the end of the world, it is only obvious because apps like Google’s new Hangouts app and Amazon’s Kindle app pass information on what you’ve seen and to where between devices, making it a coherent service completely unchained to the specific device you’re using – you can start a chat/book on one device and transition to another device without a hitch. I especially am a fan of Hangouts’ extra step: if you see an incoming message on one device, it will remove the notification from all the other connected devices (and will even minimize the open windows in other Chrome browsers).
This sort of abstraction is a common theme in the technology industry – where new companies and technologies emerge to simplify new sources of complexity. Its something I believe is becoming key functionality as the underlying problem (people with lots of devices and lots of services) grows. My advice to developers and entrepreneurs out there: don’t assume your users are married to any particular device and help them stay in sync. They will reward you for doing so.
