I can't afford what I want.. but what I would like is something like this:
Decent living room TV connected to the internet in some way (probably a small PC would be preferable to a "smart TV" then I don't have to navigate some proprietary browser system) as well as a gaming system suitable for local multiplayer. If the TV doesn't have a disc player integrated then I may need one of those (or put one in the small PC) Also probably one of those sound bars because I am not enough of an audiophile to care about the minor advantage of multiple speakers all over the room.
Mostly used in a living room/around the home would be a tablet device mainly as a more versatile internet solution than the PC connected to the TV
Then perhaps in a spare room a more powerful PC with a decent monitor (again I'm no technogeek so I don't need a 30" monitor or anything, actually I think my current bedroom TV (19") can act as a monitor... although it's only 720p so I would probably get eye strain using it as one, so maybe skip that idea)... Perhaps a touchscreen monitor so that Windows 8 actually makes sense.
Then a smartphone for when going out.
The PCs would naturally be running Windows (I'm personally happy with 7 unless I have a touchscreen, but by the time I get ti implement any of this 7 will probably be defunct anyway)
I would like the surface pro tablet too, which will be Win8, and could also serve as an alternative to a laptop for a portable work device.
I guess with all that Windows around it would be useful to have a Windows 8 phone too, though that is the one bit I am more hesitant about as I have never tried one... if not then I would probably go Android.
I'd also want to be able to use the tablet/smartphone to remote control the PCs, which would probably work better if all devices use Win8.

If I have the money I would then probably want to wire up the whole place for sound... at least a decent speaker in each room all linked so I can listen to music all over instead of just one room at once. (and control which ones are on or not with phone/tablet)
That would do me nicely.
The games console would likely be Nintendo (Wii U for the forseeable future, though I don't have any plans to buy it near launch atm), I really don't see the point in buying an Xbox if I have a PC connected to the TV. If money isn't an issue I would go for Sony as a secondary console. Not really bothered about handhelds now, so I definitely wouldn't be when I have a smartphone.

So:
Music: My small library of CDs I bought years ago plus Spotify free through the living room PC, or as the surface Pro is a fully featured computer it would work on that too (you need a paid spotify service for ARM devices)
TV: Freeview (I think all UK TVs come with it integrated nowadays) is perfectly fine for scheduled programs, other stuff I can stream online through the browser
Film: I generally just pick films from scheduled TV, or occasionally stream them. I might consider something like LoveFilm or Netflix but I generally don't watch enough to consider them worth the money.
Gaming: Wii U (and possibly PS3 or 4) in the living room, maybe get a controller to play some PC games (through Steam) there too. Other PC games played on the better PC in a spare room. Probably wouldn't do any app gaming at home, but light entertainment would be nice on the smartphone. Not sure what I would do with the Wii, might give it to my parents for Wii Fit, or maybe store it away so I still have the posibility of playing my remaining GameCube collection.
Oh, I'd quite like an e-reader too, bought one for my dad last Christmas and I like it, currently my reading is done in good old fashioned paperback and some free internet fan-fiction... if I could get an e-reader that I could copy text files to that would be awesome, as e-ink is so much nicer on the eyes than a normal screen.
After initial purchase the only remaining costs with this setup would be internet, phone and electric bill as well as actually buying games. So upfront cost (minus the speaker in every room bit) would be probably be under £3k, possibly under £2.5k depending on the phone contract (the surface taking up an annoyingly large amount of that, so that would probably be a late addition unless I need it for work) Then I don't really need an uber internet connection (currently get around 10-15Mbps, though we are in a transitional stage as the contract was for 10Mbps, but soon the lowest Virgin will provide is 30Mbps) so with a land line maybe £20-25 a month after the usual sign up deal ends, and £20 or so a month for a phone contract.
