Several people have asked about the physical size of the Gigaset DECT handsets compared to other gear. Then I remembered that Michael White of E4 posted a pic on TwitPic a while back. The pic originated in a Ustream feed.
These are (left-right): Polycom Kirk 5020 in a mug, snom m3, Gigaset S67H, Gigaset A58H.
Guess which ones support wideband?
