First, I want to thank the Macrumors community for all the good help and guidance you've given me thus far. I participate in a number of different sports, politics, travel, etc., communities and this is by far the friendliest. Thank you. With the help of a few of you, I recently purchase a 2ghz White Macbook (MB881LL/A). It's awesome. I love it. Because of the relatively small HD (120GB) I decided to upgrade that and, while I was at it, go from 2gb to 4gb of RAM. I've sorted through a couple dozen relevant threads in this forum and read the applicable guides. I've looked at Crucial & Newegg to see what else I can find out. After all that, I still have some questions. Part of my questions have to do with my ongoing quest to find the best value point. I define that as being where size/quality intersect with price. So, if you know of a better place/price to buy the things I'm listing below, by all means, let me know. First, the Hard Drive: As far as I can tell, the value point for HDs is 320GB. And the highest rated on most of the places I looked (Newegg, Amazon, etc.) was Western Digital. Thus, I've pretty much narrowed it down to two drives (though if you know of a better alternative, let me know). They are: HD1: Western Digital 320GB Scorpio Blue 5400RPM for $59.99 OR HD2: Western Digital Scorpio Black 320 GB 7200RPM for $72.99 Maybe they can be bought cheaper elsewhere? Maybe there is another drive that is demonstrably better? Is the 7200RPMs worth the $13? Anything I've missed? And now the RAM: Ram Option 1: 2 of Kingston - Memory - 2 GB - SO DIMM 200-pin - DDR2 - 667 MHz / PC2-5300 - unbuffered OR Ram option 2: Kingston Apple 4GB Kit 667MHz DDR2 SoDimm Dual Channel Memory (KTA-MB667K2/4GR) OR Ram option 3: Crucial CT2CP25664AC667 200-Pin SODIMM DDR2 PC2-5300 CL=5 Unbuffered NON-ECC DDR2-667 1.8V 256Meg x 64 2GBx2 4GB Kit OR Ram option 4: 2 of Crucial 2GB 667 Mhz CT25664AC667 DDR2 200-Pin SODIMM Laptop Memory Here I am unsure of quality and compatibility. Obviously the two Crucial options are the cheapest, but the Kingston combo pack is the only one that says "Apple." Are they just trying to charge Apple customers a premium? Which should I buy? Or are none of these good choices? I shop with Amazon because I've bought a lot of stuff from them in the past and the shipping is cheap (free), but I'm not necessarily wedded to Amazon. I'll go wherever I can the two of these things (HD & Memory) for the best possible value. Thanks again for any help/guidance/clarification you can provide.
