I bought the Xbox One Day One edition and I'm sorely disappointed. I, like you am a Microsoft geek. I have a Nokia Lumia 920, a Surface 2, and HP Probook running Windows 8.1, My work computer is a Dell Latitude running Windows 8.1, I have an Xbox 360 and I work in IT with Microsoft technologies. Sometimes my coworkers even poke fun at my Microsoft Fanboyism. Out the gate the Xbox One didn't offer me anything special. I don't have cable TV and even if I did, the Xbox doesn't support much up here in Canada in that respect. On my 360 I spent a lot of time using that console: Half of which was gaming and the other half using either Netflix, or streaming video or music from my home media server (a 2TB hard drive connected to my home laptop with the video library shared).
Playing games was not fun at first. Support for parties wasn't great, the console didn't come with any games, and the sound (which I relied heavily on for my gaming experience using my $250 Astro gaming headset) was a terrible experience. Fortunately much of this has been fixed. I had to buy the chat adapter and go through the complicated process of configuring it to work with my equipment and the console update dealt with a lot of other things such as the addition of Dolby surround sound through the optical audio S/PDIF out and enabling party chat by default. By the time all of the issues were fixed that made the Xbox One an okay experience for gaming, deals had started and I could have got a console and Titanfall for the same price I paid.
My media experience from the console that aims to rule my living room, has not been great. Netflix works fine (so long as the Xbox Live service doesn't have a problem like yesterday evening where it did not recognize my gold membership), Although I will say, each release of the Netflix App to the Xbox consoles gets worse and worse in terms of features being removed or changed drastically, but that's Netflix's fault not Microsoft's) but the fact that I can't easily use a system video player to stream content from my media server to my xbox one seems like a massive oversight. It is in fact intentional I'm sure, as Microsoft would love for me to view my video content through Xbox Video. Unfortunately at the current Xbox Video price point, this is not something I'm prepared to do. Should the Xbox Video service ever offer a subscription service like Xbox music (which I also have) I will be all over it. I understand I could open videos on my surface, from my network share, then use the play to feature to play them to my Xbox, but that is a bit of a pain in the rear to me (first world problems)
Reader's Digest version: The Xbox One has great potential but was/is underwhelming at release. The Azure backend is amazing and powerful and there are plenty of really awesome games coming to the platform. The lack of support for areas outside the US for television as well as what was surely the intentional omission of a system video player that plays content from your network make it not much of a living room ruler for me, I still use my 360 for that. I would say go with the Xbox One, just not right now. Wait until the console is updated, the games are out and maybe even grab it at a deal.
