I like the fact that it can ring both my cell and home phone when I get a call. Also, if I'm on the computer, I can do my texting there instead of with the phone.
All my calls and texts are also logged on the cloud, so I don't lose them with a phone wipe.
One thing I don't like is that the text doesn't come instantly to my phone. The best you can do is set it to refresh every 5 minutes to check for new messages. If you opt to forward it to your cell #, you get them instantly, but I'm not a fan of the workaround.
