tests can be made to show what you want them to do, same with statistics. someone else may do a test and show a different story. take it for what it does for you not anyone else.

also on the whole tablet stuff. i don't see a point in them. it's like buying a moped when you can have a motorbike for the same price. or when you already have a motorbike. think only old Italian priest and nuns should use tablets just like mopeds
