Yeah, J is right. I would rather have a PC, and I have pre ordered the raspberry pi some time ago, and that will probably become the real media center when it is up and running. Meanwhile I'm pretty happy with the samsung all-share thingy ;).
Right now I'm trying to minimize the stuff I have under my TV, because the kid is too fond of remote controls and cables nowdays :P. But the PI can be attached behind the tv with dualsided tape :P hehe
