I bought my MacBook in October 2006, shortly before the first refresh took place. I am now considering upgrade a few of the specs on the computer: Hard Drive (I now have 100 GB. I'd prefer larger.) RAM (I have 1 GB. I'd like to bump that up to 2) I have not had very good luck with laptop longevity, and I was wondering if anyone had any suggestions on upgrades. Is it worth putting in money to upgrade these features, or is it likely my laptop will crap out on me in the near future and I should save the money for a full system upgrade?
