Let’s put it to a vote: Would you rather buy a 512MB SODIMM for your TiBook or iBook that conforms to the Apple specifications and costs a lot more (price=$600-$1000), or buy a 512MB SODIMM that violates Apple specs by stacking lower cost RAM chips and having twice the current draw, but paying a much llower price (around $125 to $130).
Take in mind, you have nearly twice the heat rising into the keyboard from the stacked, cheaper design. I really want to know what everyone thinks about this subject.
Vote your mind.
