Bang & Olufsen BeoCom 5

With support for two phone lines, a high-end full-duplex speakerphone, and more, the Bang & Olufsen BeoCom 5 ($TBA) might just be the world's best cordless telephone. It supports IP telephony alongside a regular landline, and features full customization — including color scheme and ringtone — on the cordless handset, as well as a gorgeous aluminum speaker phone meant to make conversations sound as real as possible, even when multiple people are talking. Just don't expect it to come cheap.
