IP Phones And The Emerging VOIP Markets,a new report out yesterday from In-Stat/MDR, says that IP-capable "end points" will help drive a projected increase of 43 percent in IP phone systems this year (compared to 2003).
"A multitude of varied IP end points will be created to optimize the multi-media user experience," In-Stat/MDR analyst Keith Nissen says. "This trend can already be seen in cellular handsets with integrated camera, video camcorder and television capabilities."
Going forward, Nissen adds that with technical feasibility "close to being a certainty," "market timing" will greatly influence the effect these devices will have on IP phone sales.
I agree. Time and time again, I've observed that enterprise and home users who are beyond the early adopter stage and are iffy about whether or not they need a new technology or appliance frequently are sold by a surfeit of compatible applications.
Full-disclosure: I've freelanced for In-Stat/MDR.
