I'm surprised that Apple hasn't come up with this already. If you are working at your Mac, wouldn't it be great if your iPhone somehow tethered your text messages to an app on your Mac so you could text using your Mac keyboard? I'm sure we've all been there: working away at our computers and having to stop to pick up our phones to text back to someone. Wouldn't it be nicer to just tab to a chat app and keep going? Yes, they do have the new chat IM app, but it only works with people with other Macs, iPhones and iPods. If anyone has found a third party solution, please let me know!
