Default Can InterWrite slow down the system?

Hi everyone!
As the mighty D2 is finally hitting the polish market and I'm compelled to buy one, I have a small question to ask. The polish version will have InterWrite installed for "polonizing" the interface and I heard that it can negatively impact the system performance. Is that true? Personally I dont need the polish language, so I wonder if uninstalling InterWrite just after buying the device would be something worth consideration.
