Lenovo Laptop Bag

I got my new Lenovo T500, and I'm loving it.
should I buy one ....
(A screen) keyboard for protection?
(B) screen keyboard?
(C) laptop bag? If yes, what kind?

Edmond is on site. There is nothing on this list, including the laptop bag, you want to buy. The laptop bag that does not make you a target and the other two as explained Edmond does not protect in the long term.

everyone is going well with their first laptop XD, they want to keep it clean, smooth, shiny
but they are all lazy and stop

So I say do waste your money, just to use it, and do not break
