I'm thinking about upgrading the RAM in my new macbook and I have two options that I'm considering: 1. Kingmax 1GB ($94.99 CAN) x 2 - 30 days direct exchange - 1 year manufacturers warranty 2. Kingston 1GB ($110.00 CAN) x 2 - 30 days direct exchange - Lifetime manufacturers warranty I'm just wondering how worth it is to have a lifetime warranty. I plan to keep this macbook for about 3 years or so. I would assume any faulty RAM would crap out within the first year anyways. What is the better buy?
