I bought this phone on a recent KLM flight to India. Initially, I didn't think much about writing a post on this phone, because most notebooks these days have a built-in webcam, microphone and speakers. Having a separate Internet Phone might not sound like a great idea. However, for an old laptop, this phone is quite handy. Moreover, there is an element of privacy, if one were to call in say an airport over Wi-Fi.
Coming to the phone itself, it is an Ultra-Slim Metallic Plug and Play Internet phone (about 7.5 mm thickness). One could make VOIP calls through Skype. It is compatibe with both Windows Vista/XP and Mac OS X. This phone is manufactured by Lifetrons of Switzerland.
Though it is a bit pricey (Euros 40), one could save on expensive phone calls whilst abroad. I used this phone a few times and I am impressed with its quality.
