The last time I was in the US, I noticed that large number of folks with mobile phones where using them like CB radios. The service they were using is called Push to Talk (PTT) and the phones had a button they pressed to enter a PTT session with the contact they had selected from their in-phone address book.
Does anyone know whether we are likely to see this appear in Europe? If so, when?
Update: Orange currently offer this service to their business customers under the name of Talk Now. However, it's only available when used in conjunction with a Treo 600. I wonder why we haven't seen any Smartphones or PPCPEs with this feature.
