I can't remember the last time I had a desk phone. Between VoIP, cellular and PBXs that will route calls from my "desk" phone (there's a rumor I actually have one, but I've never seen it) to any number I choose; I really don't see the need.
Many companies where I consult have adopted Lync for IM and VoIP... quickly making their desk phones redundant. They have access to speed dial, call logs, voicemail, corporate and personal phone directories, directly integrated with Exchange and Outlook... no more keeping multiple phone directories.
Lync and other VoIP solutions have a huge added benefit over fixed desk phones: they work with my BlueTooth headset that I already use with my cell phone. Much more comfortable than the neck-cramp inducing handset or if-I-turn-around-one-more-time-I'll-hang-myself Plantronics over-the-head headset.
