Daring Fireball has a nice post on what Apple’s iPhone 4 video chat application “FaceTime” means long-term: That we get more alternatives to cellphone networks. With FaceTime, you currently need a cellphone connection to get started, but afterwards, all communication continues on the internet, via a WiFi connection. This is especially appealing in apartments such as mine where cellphone reception is bad. We are thus slowly progressing towards true network roaming. Another piece of the puzzle is the universal inbox (which integrates cellphone voice box, SMS, fax, and email).
