The typical laptop nowadays has a 1 terabyte (TB) drive or a solid state drive (SSD), the latter of which is hundreds of times faster than hard drives were 10 years ago. RAM capacity is often 4-12 GB, screens feature large HD resolutions (and sometimes retinal displays), and battery life is about 6-10 hours. Many laptops are large enough to offer a full keyboard, are usually about 13-18 inches wide, and weigh 4-8 lbs. on average.
