I haven't been away but my computer has, actually it never came back! Hurray for AppleCare! My LCD screen went partial dark and I took it into Apple to get it fixed on the extended AppleCare program. Fixed the screen but there was a problem with the fans which they couldn't fix. So new computer and an upgrade at that! Buy AppleCare it is well worth it. This other tile is just playing around with tangles.
