Welcome to the world of tomorrow!
1st of all, because of fast advances in cyborg technology, we'll probably barely still have human body parts, this'll sadly widen the gap between rich and poor, especially in those countries without national healthcare, or at least those where these surgeries are not included in national healthcare.
The biggest advance in technology will be the ever-so-popular Brain Chip, from now on referred to as iChip in this post. The iChip will be implanted in the brain and will function as everything, and everything will be activated through thought, or at least, through certain actions within the brain. Don't worry, your brain will learn them quite easily, through a trial and error principle. A happiness regulator (possibly with limitations, so this does not become a drug) will let people decide their mood. You'll be able to download knowledge on there in later versions, which will not make school obsolete, but which will change the use of school from a place where you gather knowledge to a place where you learn skills, social interaction, meet people, stuff.
The iChip also means interaction with everyone all over the world without even saying a word, just sending thoughts. Don't worry, you'll get used to it, it'll be like cellphones/internet, only better, user-friendlier, more natural, and without doing anything.
Wallpaper will be made entirely out of plasma-screen like paper, there's a name for it, but I forgot it, sorry. Anyhow, this'll mean that you can change the way your home looks in 2 seconds, movies will be complete surround view, games (usually controlled with your iChip, as in, you feel like you're whatever you're playing as. It's quite an ingenious system) will be a lot more awesome (although the virtual reality ones are not bad as well, they're like portable systems). Sadly, the decline in the quality of gameplay and such will mean that most games will be generic shooters, casual games, tourist games and party games (games where you're an animal are also quite fun for a while). A lot of games will focus on the "look how awesome it is to walk in this world like you're really there" aspect, neglecting difficulty and gameplay, sadly. But yeah, tourist games and casual games will have a bigger target demographic. There'll still be quite some good ones, a lot of these made by old-time fans and a lot of the younger people inspired by the older generations of gaming. Game design will become a drag if the official companies don't release their basic programming, though, so don't count on these fan games too much. Just hope they find a job within the big companies.
Anyhow, yeah, games like this will replace actual sports. The gaming industry will join the body engineering industry as the biggest and most profitable industries.
Back to the house, though, modern houses will make the best use of little space, they'll all be one room houses, which can be changed into whatever you'd like it to be through use of ingenious little multifunctional nanorobotic blocks which rebuild into stuff like beds, couches, tables, chairs, whatever. They'll also be able to project light as well, which means they'll be able to blend in with the rest of the house. Temperature and air regulation will be based on the results the system gets from you iChip.
Because of the cyborg body protecting us from accidents and the iChip system reviving us upon possible death, our life expectancy will be how long our brain lives (once Stem Cell research enables us to create new brain cells, this'll mean eternal life). The nanobot cells which we used prior the the iChip and cyborg system will become obsolete, but might still be used to make sure cancer doesn't develop within the brain. It'll also be a cheaper alternative for those who can't afford the iChip.
No teleporters, sorry. Hoovercars? Probably, yes. Depends on our new source of energy. Don't worry, though, they won't be expensive because of advertisements printed all over the car (again, because of the wallpaper-system, they updates automatically), because of these advertisements, (hoover)cars become way cheaper.
About advertisements, everything you pay for won't have them (except for product placement of course, oh how much product placement there will be)(unless you buy the cheaper version, see cars), everything you don't pay for will be full of it. Some houses will have adds, but a lot will just use their walls to express themselves (lots of pure black houses, sometimes with red stuff and skulls and stuff, as well as very bright ones, it gets rather ugly. A lot of people agree with this and prefer to just use a design which looks like bricks or painted wood).
About clothes, fashion will be messed up, but the clothing industry will go bankrupt, clothes update (nanobot structures) and recolour themselves and everything (again, controlled with the iChip). Animated stuff on your shirt is a cool thing to look forward to. Again, expressing yourself becomes way easier, which will cause a lot of different sub-cultures. Some of these will refuse to adapt to technology (a rather big part, extreme conservatives and tree-huggers will be in this group). They however won't be able to converse with the other "humans" and will isolate themselves, and probably die of some variant of the flu, oh well, they deserve a mention. Silly people.
Of course there'll be projections (using light and stuff, you know), but most of this stuff is illegal outside of house because of possible confusion and terrorism, which will mean that options involving these will be limited in official versions of the iChip (hacked versions are very dangerous, though, I wouldn't advise them). iChip managing will require a lot of work to make sure it doesn't get hacked, abused, and so on. Imagine getting a virus in there ._.
Life on Mars. It's a fun place, lots of parties, but communication with Earth takes a while. All the super-rich (the CEOs and stuff) stay there, as well as their families and stuff. Not really anything else worth mentioning. It's a long trip as well, it's probably better if you'd stay on Earth, more people.
Back to hoovercars, though, using systems which were also present in the modern cars, automatic driving systems using GPS and transmitter things on cars to transfer the location to closeby cars, everything will seem like chaos, but there will be no accidents, and we'll all be going very fast. If we do use hoovercars, the ground will be filled with houses, modern places usually have no front door, but rather access through the roof by using the nanobots. You'll just walk around on the roofs trying to find your house, you'll have 4 direct neighbours, fun times. (Don't worry, these walls are practically soundproof).
If you don't get this, imagine a grid, every square will be a house. You use your iChip to open the house, an elevator will form using the nanobots, and you can go in, go down, and transmit "honey I'm home" to your wife's iChip.
And that's it, really. It'll be fun if you can afford it.
