We have only just got these phones for our new house phone. I must say they're very good. Much better than the old ones I had. A great thing about tem is that they suprisingly look very smart. Usually house phnes look hiddeous but i woulndn't mind a moblie looking like this.
Also it's got a great picture quality and it is a colour screen. Everything is so clear on it. Another obivious great thing is that it's wireless. Moreover you can very easily store quite a few contacts onto this phone so it saves you typing the number in all the time.
Compared to a lot of house phones, they are actually quite small. Very ergonomic (how it fits into your hand). In addition, you can very easily chnage what rooms you have the phones in. Finally, I was amazed at how good the sound quality was. I could hear people perfectly and you can very easily understand what they're saying.
At this time i can't think of any disadvantages
deffinately a phone to get if your looking for a new house phone
