They might sound like geek superheroes, but these two services offer some interesting communication capabilities. Mighty Text allows users to send and receive texts from their PC (as long as their mobile phone is nearby). The comfort of using a normal sized keyboard to send a text is liberating. Texts suddenly become far more expansive than the usual telegraphic efforts forced on users by tiny screens. A plugin also allows users to send texts from within gmail — only for Chrome browser users.
Pushbullet pushes links, attachments, messages and notifications instantly between any computer and phone that you add and verify, essentially bridging otherwise balkanised platforms. Works with all of the major browsers (see the image below).
