I've had this phone for a short while, I have noticed two things so far. One is that the sound from landline seems to be rather bassy, which in its own right is not a bad thing, but can be a surprise to the first time user.
Secondly, unless I have missed this, there doesn't seem to be a way to add contacts for landline use. All the functionality seems to be reserved for Skype use, which sadly I've not actually used yet, although setting up an account was very easy, as was setting up a second handset.
The phone chrages exteemly fast, once the initial charge is managed. The screen is very bright and clear. The choice of ringtones is a bit limited, but they are functional.
I like the design of the phone and it sits in the hand well. I've not noticed it getting hot, as I have had this sensation with my former Dect phones.
I have sky broadband and I had been concerned that the phone would have difficulty connecting, but there was no issue.
In summary, if you use the phone mostly for Skype, I think this phone will be a very good option. The abiltiy to set up an account on the phone is a bonus to me.
