I dislike a lot of things about the XBONE and how quickly they can turn on and off features (I can see them updating and people and there usual tendency to not read through ToS just clicking "I Agree" and suddenly all the old problems are back).
I found it humorous too that on the every2minutes contest (trying to win an xbox so I can sell it for a PS4... or just money) that it shows a red ring when you enter the code....
But yeah I'm weary of both because of that. First releases are always buggy because they haven't been truly tested by the average consumer. They'll fix the issues... or not (*cough* Microsoft *cough*) and re-release slim versions. It's also the time when all the shoddy workmanship shows in the controllers and systems. If things overheat, snap off easily, ect. they will update and replace. And if you wait you usually have a much better library to choose from, unless you're the Wii U... then you have the same library from the Wii but with slightly less grainy graphics (I'm still saddened by how Nintendo has just let itself go in the higher end console department, they're still kicking a reasonable amount of arse in the handheld.)
I predicted that Sony's controllers would have issues or the console eat discs and the XBOX will have system failures. Waiting on Sony but I guess the XBOX is living up to the system failure, horrid tales of the "Green Screen of Death" is a bit haunting. And you can still troll your friends by saying "XBOX off" if they have voice enabled.
Despite my dislike of Microsoft I do want it to do well, so don't think I'm all hate. Two strong competitors mean a healthy market, if Nintendo would stop sniffing glue they'd be in this game because I liked the idea and concept of the Wii, and it pioneered some changes in both Sony and Microsoft (however terrible they turned out to be.... oh Kinect... hate you. Sony Move, hate you more but at least you're a bit more optional).
Oh if you get a PS4, go through the manual there is a voucher for 10 (or more) PSN dollars and PSN games transfer through systems. I bought Castlevania: SotN on my PS3 and can play it fully on my Vita and it will work on the PS4 :D
XBOX has the trial of Live but I think most of the Live titles transfer, they were super sketchy on if they did or not.
