I picked up a Xbox one yesterday and so far I'm pleased and impressed with it!
As for the UI, it seems a little unstructured and lacking tho. Like Xbox live games, there are no category's or generally easy browsing, I just get a list of games to sprawl through. And they've removed a section for demos, instead you have to search for them, and unless I'm mistaken there's only half a dozen on there!?
Not sure I've fully got the hang on the snapping yet, is it just a gimmick, or do you find it useful? Can you adjust the size of each screen?
I do love the streaming option to Windows 10, that works much better than I'd expected!
Not fused over putting my rubbish freesat box through the hdmi in, it doesn't work at the best of times. So I've just hooked up the chromecast through it at the moment. With the purchasable TV stick you can get, do you get freebies channels with this?
Overall, it's good, and I think will just take some adjusting from 8-9 years of having a 360. Although, I certainly want to hear about any UI changes coming and expansion to it!
