I use it to call home from here in deepest darkest frogland. Costs about 1.5p/min to make the call. Cheaper than BT!
Like when you could first download music its quite fun but when it comes down to it its a bit of a pain in the arse and will end up using a phone in the end.
I have it, It's better than MSN It's free (To other Skype users) It's cheaper than BT And if you get it, all your mates get it... I thinks its the mutts nuts...
