ClearOne has come out with surprisingly nice looking, multi-faceted speaker phone that is compatible with a variety of devices. The Chat 50 is a full-duplex (which means you don't have to take turns speaking to and listening to the other person on the line) USB speakerphone that is usable with VoIP software such as Skype and Vonage, Web conferencing software, IM software and PC gaming chat software like TeamSpeak, perfect for all the fraggers who wear ties during the day. It also has a headphone jack so you can listen to your cellphone or iPod through its speaker.
While it probably won't sound as good as Carnegie Hall, that added bonus certainly is a nice perk in the otherwise maddeningly bland world of speakerphones. At $150, it may be a little steep, but there's no denying the usefulness of being able to go from discussing stock deals to yelling bloody murder over the vanquished corpses of your online foes.
