Range and Bandwidth:
Using mobile internet access is much slower than using a direct cable, For example using a cell phone's connection such as GPRS, EDGE, HSDPA, HSUPA, 3G, 4G, 5G. All these internet access are available within a range commercial cell phone tower. Nevertheless using technology such as 3G or 4G is considerably cheaper than using high speed wireless networks like LAN's and LAN's have a very limited range.
Security Standard:
Working with a mobile it depends on the public networks used. Users should be careful as attacking a mobile device on these networks are easily done.
Power Consumption:
The other limitation to using mobile devices is the batter. When and If a power outlet or portable generator isn't available the usability of the device is compromised. As mobile computers rely entirely on it's battery for power. As mobile devices are very compact, More compact batteries with higher capacities are required. These compact high capacity batteries are normally more expensive.
Tranmission Interferences:
Terrain, Weather are easily interfered due to these reasons and the range from the closest signal point may be disrupted from normal use. Reception in Tunnels, Some Buildings and Rural Areas are usually really poor.
Potential Health Risks:
People who are using their mobile devices are typically distracted, Usage while walking or driving as a dangerous habit a lot of users face which leads to traffic accident, Questions regarding mobile phone radiation and health are raised. Such as over-exposure to blue light causing lack of quality sleep.
Human Interface with Device:
Alternate input strategies like speech or handwriting recognition need training using services such as voice control and map navigator are the examples.

Robots mechanical devices that are autonomous or semi-autonomous,
meaning once instruction is given to the robot it functions without
supervision, while other robots may require a user to give regular
instructions. 
Smartphones are essentially mobile phones that have been buffed up with an
advanced mobile operating system such as the IOS(Apple) or Android, Similarly
to Tablets, Smartphones are flat mobile computer devices equipped with a
touchscreen display, Unlike the Tablets they are pocket sized,
Tablet Computers commonly known as Tablets, are flat mobile
computer devices usually equipped with a touchscreen display, some tablets may
include a stylus (pen shaped peripheral) that allows for touchscreen use that
may require more finesse such as for handwriting or drawing. 
Introduction:
Before Laptops were a norm portable computers were used, they
were essentially built out of full-specification desktop parts but allowed the
user to move it around, and they would include the full desktop a screen and
keyboard, either packed in a suitcase or luggage bag. Though due to Laptops
being able to match the performance of some desktop computers, portable
computers started losing popularity as the ability to carry around a much
lighter and smaller device with the ability of a desktop was much preferred. 
Laptops otherwise known as notebooks, are computers designed
like a clamshell, opening and closing, on the bottom part of the clamshell
would include the input devices such as an alphanumeric keyboard some larger
laptops even including a keypad, and a pointing device commonly a track-pad,
The top part of the clamshell would be where the screen is a thin LCD/LED
computer screen, May also include a built in webcam and microphone. Laptops also have built in speakers that are
normally on the bottom clamshell. The laptop is easily closed and kept in a bag
or carried in the hands.
