Just noticing that I need to clean my MBP quite often to remove greasy smudges that clearly show the outline of the key board on teh glass screen. Anyone else getting this with the late 2008 MBP? Does this have implications when running the MBP in clam shell on an external display? i.e. if the MBP heats up will the warming of the keys cause the keyboard to stick to the glass screen? I guess putting the cloth screen cleaner between teh keyboard and screen might help.
