They are faster and very easy to carry.You can store all kind of files and folders.Yoc can also store programs.So you can install them in another computer or in the pen drive itself.They are becoming cheaper amd cheaper day by day.Nowdays you can get a 2GB pen dirve for less than 20 euros.

You should buy an inject printer, because it is cheaper than a laser printer.
Marshall: I need to print really fast. I'm not going to use colour or images. Shall I buy an inkjet printer?

The best mouse
LED mouse
The LED mouse is less sensitive than the laser mouse.
The LED mouse has more problems with suble surfaces, like shining, slick and highly polish surfaces and rough surfaces can be a problem too.
I recommend you the laser mouse because you will have fewer problems with the surfaces.
