Good: Easy to set up and install, good call quality (some static after 20m, but better than my regular cordless phone), has lots of features. (Although I did not set it up with a landline, so didn't test conference calling, switching lines, etc.)
Bad:
1) The phone automatically syncs with your skype contact list but does not indicate status, so you have to check the computer first to see if someone is online! For me, this was a deal breaker, as the whole idea of having a cordless skype phone was to get away from the computer.
2) If you accidentally answer a call on the computer, you can't hear or talk to the person, but you also can't use the phone -- it just says "skype in use" and won't pick up the call! Again, deal breaker.
3) You can't use skypeout to dial in a number -- you have to go to the computer, add the number to your contact list, and then select it from the phone. Major deal breaker.
4) You can change your skype status from the phone (to offline, away, etc.) but you have to negotiate 3 or 4 cryptic menus to get there. (Minor annoyance.)
5) And the last complaint is actually with all skype phones: Once installed, the skype app on the computer becomes useless unless you manually change the audio/microphone settings every time you want to switch between phone and computer. If you want to do a video call, you still have to use the phone to talk! Why doesn't Skype have an easy way of switching between profiles?
