Continuous Client. If you need a refresher you can read the article here, but the gist of my argument is that the work you're doing in applications on your phone, tablet, or PC should follow you around. You shouldn't have to restart each conversation or refocus your Twitter stream or re-open applications and load up files you were working on. Your devices (and their clients) should talk to each other so that you can placeshift your session from screen to screen.
Well, believe it or not, someone took this to heart. The makers of the super-popular chat client Trillian have implemented Continuous Client features in the latest beta build for Windows (5.0 build 30). Amongst the new features added is the ability to share chats between devices "in realtime," allowing you to switch from PC to phone to iPad without losing the thread. Using "presence technology" the client can make logical guesses about when you're at (and not at) your PC or phone, and reroutes your notifications accordingly. The company has a blog post on all of the features of the new build, but of course, the best way to experience it is to download the software and try it out for yourself. We'd love to see your reactions and find out if it's making life easier, so sound off in the comments below.
