ON Laptop

I am planning to buy a laptop the soonest possible, i am really having a hard time on my reports especially if im away from the office, this need actually comes when the management requires a lot of reports from me specifically, i am a bit worried if i will just rely on my usb, hence using the usb in any computer will bring harm to my files, i should do the purchase this month. I actually canvass a stylish laptop worth 20k but im hesitant if its durable, have to check the brand first and consult it with my friend who is a computer expert..haay life,,so disgusting!
