I'm still a recovering iOS user and one of the things I miss most about iOS is the ability to message people directly from my computer in addition to my phone. In search of an app that offers similar functionality, I've been using mySMS to some degree of success. It works, but has freakouts once in a while (e.g., double messages, etc.) and often gets hung up with group messaging/MMS messaging. Are there alternatives that offer similar functionality; i.e., the ability to text via phone or computer?
