Each type of ICT has its own advantages and disadvantages. Desktop computing is the most powerful and versatile, but also the most expensive. Laptop computing is more portable but still has good performance. Tablet computing is even more portable but has reduced performance. Smartphone computing is the most portable but has the least performance. Wearable computing is the most portable but has the least performance and is still in its early stages of development.
