Lastly, we have the ThinkPad Twist, a business-class offering that is more in line with some other convertible laptops we've seen. The screen flips down and swivels around to cover the keyboard, converting it from an Ultrabook-like laptop into a husky tablet.
Mainstream and Premium Models
While the entire laptop category has gotten slimmer, there's still a market for larger desktop-replacement laptops that blend premium design and function. Desktop replacements aren't quite as easy to cart around as smaller ultraportables, but these 14- and 15-inch laptops offer everything you need in a day-to-day PC. They have bigger displays, a broader selection of ports and features, and are one of the few categories that still offer optical drives. Screen resolutions run the gamut from 1,366 by 768 for budget systems to the more mainstream 1,920-by-1,080 resolution, up to the 3,840-by-2,160 resolution found on high-end multimedia laptops intended for graphics professionals.
Laptop charging trolleys are also used to deter and protect against opportunistic and organized theft. Schools, especially those with designs, are often prime targets for who steal high-value items. Laptops, netbooks, and tablets are among the highest–value portable items in a school. Moreover, laptops can easily be concealed under clothing and stolen from buildings. Many types of laptop–charging trolleys are designed and constructed to protect against theft. They are generally made out of steel, and the laptops remain locked up while not in use. Although the trolleys can be moved between areas from one classroom to another, they can often be mounted or locked to the floor or walls to prevent thieves from stealing the laptops, especially overnight.
