Found this article/review of an Android app called AirDroid. QR code to Android Market below. Of the many features this app provides my favorite is the ability to send/receive SMS messages. When I have my laptop on and the phone is nearby I would prefer to be able to respond to messages via the laptop instead of picking up the phone.
Other features allow you to import/export music, photos, files etc.
Very simple setup. Even very novice users should be able to connect your device across the wireless network to your desktop/laptop.
Thanks for reading,
