I would usually be cool with this transition, newer is better, right? But I honestly can't see anything "new" in newer versions of Skype. Chat, voice, video... still the same, just more RAM usage, more FB integration nags, and more ads. Also lack of API - which borked my PBX system.
I can't receive calls anymore on my PBX, I would have to purchase SkypeConnect. 7-8$ for having ONE Skype SIP channel? Geeez... for that kind of money, I can buy a few virtual phone numbers in the US, Canada and Europe, usually with more than one inbound call channel.
I'm just wondering how long will all those Skype-enabled TV hold on before a newer version kills it too.
