You know, 15 years isn't a long time really. Hell, I've been posting on this BBS for 11 years. In this relatively modern timeframe I think we might see:
1. Augmented reality becoming more useful/ubiquitous. Possibly in the form of Google Glasses type devices. The theoretical ability to record everything you 'see', and the associated rise of the citizen journalist (a trend started already) but not sufficient technology to categorize it or make sense of it all yet. Limited Agent-type artificial intelligence will assist you with this and with common tasks such as ordering groceries or doing deep semantic searches of the Internet.
2. Continued moves away from traditional PC formats to cloud-connected ubiquitous devices centred on the mobile phone and/or tablet. Many home users will stop buying traditional PCs, and instead interacting with the Internet via connected televisions, tablets, and other household devices. Touch and Voice user interfaces will become more important relative to the Keyboard and Mouse, especially in the home, where people will use Touch or Siri-like software to do everything from order groceries to set the timer on the washing machine to changing the TV channel. People typically own many devices, in many innovative form factors (including paper thin OLED tablet and wallpaper television type devices) all of which synchronise with eachother automatically (provided you stick to the same ecosystem, e.g. Google or Apple).
3. The death or near-death of broadcast television except for live events (sports and news). People will use connected streaming TVs which are much more interactive and allow people to pick and choose what they want to watch for various price plans. TV channels/networks will cease to be important, instead people will buy directly from the big content producers, and indie labels, much as has happened for Music.
4. Hybrid and electric cars will become more commonplace, and better/more efficient, largely driven by higher petrol prices rather than concerns about global warming. This will in turn drive battery technologies forward for other devices. Quick charing for battery-powered cars will become more common, although Hydrogen fuel cells will still be some way off.
5. New drugs from treating common cancers and certain other critical diseases passing their clinical trials and becoming more readily available. Some alternatives to immuno-supressants for transplant patients, and some developments with rejection-tree transplants via tissue engineering, but no cloning or 'growing' of organs yet. Continued improvements in the artificial heart and other artificial organ designs to the point they become relatively commonplace as a bridge to eventual transplant or for those who are too old or too sick for transplants to be viable.
