Secure Laptop for a simple user Unix/Linux and Windows 7

Hello

I have a problem: want to build secure laptop for simple user ( that’s me ) with the VPN and virtualization.
Laptop would be for work at home and travel , so security for wirelles networks and comfort using Mobile 3G internet with dongle (not to have problem with drivers) is also important.
I have always worked on MS Windows environment and the main programs which is used :
MS Office
Adobe acrobat and other programs to work with PDF
Simple programs to work with pictures ( such as MS Paint )

Skype and Email
Browser ( Chrome or Commodo Dragon)

UTorrent and Strong DC ( for soft , movies and etc. – basically entertainment porpoises)


What should be the best composition of the OS systems ?
Which VPN provider would you recommend?

Is there any other software or hardware , such as external box ( VPN/Firewall + ? ) that could you recommend ?

Or just describe your vision for a safe laptop designed for simple user (not programmer) and for travel

Thank you for you time and answers
