I totally agree with you. I don't want to disdain Skype, which is a great tool for its intended audience (the noobs, the moms and paps, the grandmas, etc). Also, Skype technology was almost incredible when they first appeared, so .. lots of respect for their history and accomplishments.

But I also think there is a lot of room for "Skype Killers" in different niches. I think Skype UI is getting worse for the experienced/heavy user. What is your niche? Would love to hear more.
