I just picked up a MacBook Pro (base model).
Front Row seems to be a very laggy program, navigation lags often. After it closes, OS X seems a lot slower. My itunes has skipped, the volume controls lag. Twice I have checked activity monitor and have seen "rcd (not responding)". I googled it and it seems to have to do with the Front row app.
This most recent incident, I had to kill rcd again, and noticed that the Front Row app was using 330 MB of memory

. That time, all I did was play a song in it, then ESC out.
I have a total of 512mb (waiting for my ram upgrade to come in the mail).
Is there something wrong with Front row? It seems to also take a few presses of the remote before Front row even activates.
I've had the macbook about 3 hours and havent touched the factory install.
