If you have an Android phone, you need MightyText.
SMS messages are a pain in the neck no matter how quickly you can flit across the keyboard. Install MightyText on your phone, install the Chrome extension on your PC, log into your Gmail account, and MightyText consolidates all of your SMS messages, relaying them from phone to PC and back, dishing them up on a machine that -- hopefully -- has a bigger keyboard than your phone. Maybe the monitor’s better, too.
SMS is dying, or so I’m told. Until it’s completely kicked the bucket, MightyText is the best solution.
