I have a Medion desktop PC at home. And Windows Vista runs with a 1GB memory is not really outstanding. After looking long, I decided for this model. About the shipping Amazon I need me anyway not comment because this is indeed world class. Yesterday I then got the 2Gb memory of Kingston and get the same easily integrated into the PC, then turned on the computer and looking forward. Without my help the whole 3Gb be detected and the computer is now running super smoothly and without waiting until a open folder loaded. And the value for money is right. What if you had previously paid for as an upgrade? Conclusion: Super simple but meaningful upgrade for little money.
