Big news today from SIPphone, the company that brought the Skype competitor, Gizmo Project. The "All Calls Free" initiative kicks off today and it although it sounds great, there’s a slight catch as well as a problem that keeps me from using Gizmo in lieu of Skype. The "catch" is that you can only call people that are registered Gizmo users and only those mobile or landlines that are in their profiles. SkypeOut, by comparison, provides the ability to call any mobile or landline. Granted, not all of those calls are free at this point, but it’s an important distinction.
The main reason I’ll stick with Skype? They have one key element that Gizmo doesn’t yet offer, and that’s a mobile client. Gizmo works on Windows, Mac or Linux while Skype adds a client for Pocket PC and Windows Mobile. That mobility and flexibility will keep me on Skype for now. Gizmo is making strides as they just introduced a client for the Nokia 770, so I expect we’ll see more on the mobile front from the Gizmo folks. How about you? Does a mobile client outweigh additional free calls?
