I've always been frustrated by technology that doesn't work as advertised. And maybe it's just me. But it seems like this happens more now.
There are all kinds of examples of this. Windows 10 and its terrible updates. Universal Windows Apps and their unsophisticated capabilities. Miracast, which disconnects randomly like a parody of Chromecast. Skype, oh glorious Skype, with its many ills. And the Philips Hue updating process I ranted about on yesterday's First Ring Daily.
