Hi Imperfect1 - Yes, Skype works fine for me - all parts of it, although I have found that once in a while I do get a "bad connection", so to speak, but redialing the caller usually fixes the problem.
I do have to say though that Skypes quality isn't quite what it used to be several years ago. It seems like the more customers they get, the worse their service gets - they also recently doubled the price for non-skype out calls (that is calls directly to a land line) although it's still really cheap. When I first started using Skype it was ALL FREE.
I use skype with a Logitech WIRELESS stereo headset and boom mic so I can walk all around the house while on a Skype call - pretty cool (the Logitech wireless headset utilizes a small USB thumb drive sized "transmitter"). It's not bluetooth so there isnt any pairing tasks. I get about 35 feet of range.
Haven't tried Goggle Talk yet but thats completely free until 2012 - I guess it's supposed to work like Skype but without all of Skypes features. If you ant to use it all you have to do is get a free Gmail account
