Hi, Does anyone have experience with the silver-backed version of the Xoom compared with the matte black one? I'm in the UK, and it seems that the silver one is the only one available at the moment. Does anyone know if the black version will be coming to Europe, or should I dive in and pick up a silver one? Which backing would be the better version to have? I've read that the silver doesn't pick up fingerprints so much, for example... Thanks!
