21st century designs
* Firstly new world could use new keyboards with hexagonal keys; they offer more adjacent keys than square keys so it could change the way we type and also increase the typing speed as alienware laptops are called 'alien' we can add this feature and see if people like it or not. The mouse pad also could be added a different shape flavour. When you open a laptop you see everything is square or rectangle - is it really important for a high tech laptop to be like that ??
*The laptops that developers use are high spec and most of them dont worry about the wieght the laptop has but the specs the laptops have. They dont want systems which couldn't suffice their needs. So we can put high end laptops in a suitcase with cooling systems on it so the person has to just carry a hard suitcase with and not a bag with a cooling pad and laptop and port extensions along with. So we have plenty of space in the suitcase of thickness around 3 inches - today thin systems are expireincing over heating and high end users dont like heat which scorches the batttery which could also be added in the case so users need not worry about going anywhere with a charger which could can be also added to the suitcase which has a retractable wire. Later we can add solar panels for charging on the go to the suitcase. Many ideas are there in everybody's mind now and who in this world would refuse to buy a system with this many features included even though it might weigh around 5-7 kg.
*the angle of webcam in our laptops is just the same as the screen with our eyes so when we look into screen the cam will see our face a bit down so while video conferencing we cannot maintain eye contact with the person in front of the screen while typing as we cant look in camera as well as the screen as well as the keyboard. So the camera could be fixed at an angle with the screen which would cancel this effect.
*leapmotion sensors can be attached to the laptop itself and could be dettached and worked with wirelessly.
