The ideal cordless phone

My ideal cordless phone would have

  • Caller ID
  • Headset jack
  • Single-push (on/off) Mute button
  • Ability for user to insert ?1? in front of caller ID numbers so I can call some people back
  • Belt clip
  • Speakerphone in handset
  • Full duplex speakerphone in handset
  • Address book that overrides caller ID strings so I control which names appear
  • Big address book

And some subjective things:

  • Feels good in hand
  • Good microphone (for normal and speakerphone use)
  • Good speaker quality
  • Good speakerphone quality

I?m leaving out ubiquitous features like redial and number buttons and a screen backlight.
