Of course, this should come as no surprise to the Skype user who buys Skype-Out time and finds out what a PSTN handoff sounds like.

A fascinating technical article by Aswath Rao and referenced by Om Malik drips tepid water on Skype’s technical claims. Does it matter? We think so – but not necessarily for technical reasons….
