Query: Good Sound Quality, Hard To Use

I have found the speakerphone sound quality of this phone to be quite good, as you would expect from a Polycom product.The trouble with this phone is its stunningly poor user interface. Bringing up the call history list is an exercise complex menus and confusing button placement. The screen is not back lit, making the display hard to read at most angles and conditions.It's a nice phone in some ways, but Polycom's design makes it too frustrating to be worth it.
