Those DIMMs may not look that special, but they’re secretly sweet. These DDR3 modules are much faster and use less power than what you’ve got in your laptop right now, although I’m skeptical that laptop RAM uses more electricity than, say, the fans (especially in a high-performance laptop). Still, any saving of power is welcome, especially when your main concern with a laptop is battery life, not performance — no one really even wants to max out the graphics on their laptop, it’s just not done. They want to be able to play WoW sitting in the sun at a cafe for 3 hours, not play 20 minutes of Crysis (although, as I’m finding out finally, Crysis is pretty awesome).
