MightyText just sits there as one of my Chrome extensions and lets be text my gmail and other contacts from my desktop and then the responses pop-up and also appear in my email (if you desire). Very cool and virtually no overhead. All integrates between mobile and desktop. Free and PRO versions - after using for sometime I may the minimal investment for the PRO version.

Only possible complaint is the number of notifications MigthyText triggers although I'm sure they can be minimized or turned-off - just haven't found that yet. Review collected by and hosted on G2.com.
