Over on his blog, Jeff Pulver asks "Do you prefer softphones or IP phones?", which is a great question to ask. What do you think?
I left a comment there and then started writing a longer blog entry - but I just don't have the time to complete that particular entry, so I'll have to stick it in the queue for a future article. In the meantime... do head on over to Jeff's site and leave any comments you have. It's definitely an interesting question.
