I had not come across Pal Talk and therfore can not comment on the quality. As Mark has commented, they only offer Windows versions so, especially in the light of what MMario has reported, I think we are better of sticking with Hearme and hoping that they do get their act together soon.I also noticed that the minimum specs are different and PalTalk asks for a P166 comared to a P100 and a V90 modem. I know that Jeri, who has a V90 modem can only get a 28K connection because of phone lines and that it seems to be fine for hearme.
Another drawback is PalTalk seems to require adding email addresses and maintaining a list of contacts whereas with Hearme, it is a simple matter of visiting a web page.
Thanks Mark and sorry to sound negative - this is just my assessment and I hope it is a reasonable one.
