Umm I think desktops will still be the same, maybe just smaller parts like smaller mobos, matx will become standard, laptops will become alot thinner as faster components become more affordable. We will probably see larger oled screens like 21" and they will cost about 600-700 for that size. Cellphones will also get thinner, along with larger screens and better cameras, more functionality such as querty, probably some type of faster connection to the web. Better battery life. Televisions will start coming in oled in small sizes. Regular HDTV will be alot cheaper, and of course in feb 2009 every TV will have a digital input. Portable gaming systems such as the psp will be touchscreen probably, or maybe somewhat interactive with your body. Microsoft should make a portable gaming device. Everything is gona be blue tooth wireless keyboards, bluetooth gaming mice, wireless surround sound, smaller speakers and thinner but louder subwoofers. Every picture in your house is going to be a digital photo frame. The fishtank will automatically feed the fish, kill the algae, purify & heat the water, and clean everything else. The dog will be walked by a device that will control the dogs brain. The litterbox will automatically disopse of all the waste.
If you don't care to read the whole thing, basically, i think it's going to stay somewhat the same. Technology will slightly develop, but I don't see any drastic changes such as flying cars or robots. Look at how far we have come in the last 30 years, what do we have? Internet, LCD's, digital tv signal, cellphones, and computers. But, in the last 5-10 years, all we really have is just HDTV. Basically TV is almost at it's best. Sound is also at the best quality, basically all we need are wireless solutions such as bluetooth to become more widely available.
