Laptops are quite better than netbook so i would recommend you that you should buy a laptop instead of netbook since laptop is better than netbook both in feature wise and in look.
At $300 you cant get a good lappy there i will suggest you that you should go for a good netbook.
In my opinion you should buy Acer inspire series netbook...
If your netbook has Wifi router then only you can use wireless connection anywhere in the world but ya if you are having plug to surf then too you can use internet anywhere in the world..
I think that through bluetooth you cant use your laptop internet connection on your mobile.Your mobile should have wifi then only you can use internet from your laptop on your mobile..
I think that future computers will be based on artificial intelligence which means that they can do anything which we can do.i.e they can talk,walk,take decision etc..
I think that a booting virus is there in your computer which makes your computer restart again and again.May i know which antivirus you are using on your system currently..
I think that the problem is not with your laptop but it is with your wireless broadband.Please check your wireless broadband and see whether everything is connected correctly or not..
If you are using such softwares and you have license then it is not illegal but if you are using such software without licence then ofcourse it is illegal..
