RIP Skype ?
I do not keep Skype open any longer at home PC, because 1) it started displaying ads even though I am paid customer and 2) sometimes its chat window would lag by minutes, making it unusable. On the other hand I've been using SIP since last 3 years (with AA ISP and Panasonic phone) and am no longer tempted by cheap international rates in Skype. I have cheap international rates on my SIP too, and I can use it without being tied to a PC. My only regret is there is no good chat service to replace Skype, but perhaps I will simply setup my own for friends and family. If I actually need it.
I feel a little sorry for the chap who was using Skype for VoIP, but really he should have moved on to proper SIP.
