Can I forward/reply calls/sms to PC? I wonder if its possible to forward calls or sms to PC where I can then reply or at least get notified of a call/sms? For example, calls might be forwarded to Skype, isit possible?
Edit 2014/06: I've moved on and developed MAXS. See my answer here.

Original Answer:

GTalkSMS (Google Code Project Page) is a alternative for android-notifier which works over XMPP (GTalk, Jabber). It allows you to control various aspects of Android, includes a SMS/Call/Battery notification and reply system. Additionaly it is able to send and receive files to and from your Android device. There are many other features too.

Using XMPP as transport, the "desktop app" can be every XMPP Client. Which is one of GTalkSMS big advantages, as it does not need a dedicated desktop app.

Note: According to the FAQ I have to disclose that I am involved in GTalkSMS. GTalkSMS is an open source GPL licensed Android app. Everyone can contribute.
