While I would not have ranked these in the same order the following 10 reasons will point tablets overtaking laptops in the next year:
- Power consumption
- Viruses (lack of)
- Portability
- Cost effectiveness
- Online connection
- Available applications (especially on the iPad)
- User friendliness (my number 2 ranking)
- Bluetooth connectivity (my number 1 ranking)
- Efficiency
- Social integration
Laptops will still serve the purpose primarily as input devices at least until the tablets mature to the point were they do this better as well.
