Laptop have the advantage that we can carry our computers as we wish. However a lot of us have concerns when travelling with laptops so I think I reproduce this FAQ made by a friend of mine for the benefit of Digit Readers. 
Can I carry a laptop as check in baggage in planes?
Yes you can, but it carries the risk of getting stolen or facing the extreme handling of check-in baggages. Your laptop is best kept with you in the cabin as a hand/cabin baggage as it is safe from theft or torturous handling this way.
Can I use my laptop on short haul flights?
Yes, you can use your laptop on short haul flights if there is enough battery power available and the airline permits using it while on flight. It is best you confirm the case with the airline while booking or while boarding the plane. Normally all electronic items are switched off before take-offs and landings. Laptops can be used while in the air a while after take-off and a while before landing when the announcement is done.
Will airport security screening hurt my laptop?
In most cases, no. The baggage security screeners at airports use X-rays unlike the magnetic metal detectors used to screen humans. X-rays are safe and harmless to laptops and would not cause any damage to the laptop in normal circumstances. Keep a backup of your hard disk in case the screener uses magnetic fields which could corrupt data (such scanners are very rare, however).
Can I use Wi-Fi hotspots while travelling?
Yes you sure can. But you have to remember, open and public hotspots like those in coffee shops, airports, parks, etc. are usually unencrypted. This means your private data can be spied on or stolen by data thieves and hackers, in that case sensitive transactions are best left to secured internet connections.
