Statements
1 Good for people with disabilities to carry around as a communications tool.
2 Bigger monitors can double up as TV screens.
3 Can have powerful components that use a lot of power.
4 There are lots more cables and wires to deal with.
5 They are more likely to get stolen.
6 They are prone to damage, e.g. thin screens, easily damaged by spilt drinks.
7 Can be transformed into a desktop-style computer by attaching an external
mouse and keyboard.
8 Suited to people on the move.
9 More powerful.
10 The keyboard is more comfortable to use, with keys better spaced out.
11 They are less likely to get stolen.
12 They are more likely to have ergonomic devices that can be attached to the
computer or used around it.
13 To transfer files, you have to save them to a medium such as a CD R and move
the disk rather than the computer.
14 They are likely to run on batteries, which need recharging. More powerful
programs use more power, which requires frequent recharging.
15 They can run off a battery in situations where electricity is unavailable.
16 You can store files to the hard drive and take the whole device with you,
rather than having to copy files to another medium.
17 They are good for parents who want to see what their children are doing on
the computer.
18 They are big and bulky.
19 They are not so easy to upgrade, as components are compacted into the
device.
20 They are more expensive for the same specification.
