Almost every Toshiba we have had has given problems from day 1.
Medion - you really are joking.
I know plenty of people who got Toshibas, some old, some new and they all work fine, never had one myself mind you.
As for Medion, again I know a few people who got a medion and have had no problems with them apart from one of my brothers and that is because he kicked it. someone left it on the floor and he did not see it there.
Depends on what you want the machine for and how much you want to pay. If i was going for another laptop which i am not because I don't like them that much, I would either go for another Asus or a toshiba.
