Portable Internet Dongles - Solution

Hello Friends, one of the possible solution that i came up with is:

Changing the motherboard with an on-board supportable feature of Internet. You must be thinking, then what is Wifi. This is not Wifi, this will be like a portable internet which you can recharge or refill like your balance on the phone. The chip will have a special id and this id will have to be given to the telecommunication companies and they will recharge you directly. 

You can do this directly via online payment. This will help people to start the internet any time they are in an urgency. 

Advantages:

1. No need to carry the Portable Dongle.
2. Instant recharge any time
3. Online refilling of the data packs 
4. Simpler way to Connect 

Disadvantages:

1. For those who know Mobile Tethering, they might seem a bit upset and think what is the use of this technology. (But many people are not tech savvy and they need as much convenience as possible.)
2. Big loses in terms of Dongle selling to the telecommunication companies.

Please feel free to add any advantages or disadvantages.
