Hey all, I'm finally home from college for the summer and with a job I have a steady source of income for the next 3-4 months. I would really like to upgrade my PowerBook's internal memory. I have a 15 inch Rev A. Aluminum book, and it has the stock 2x256 MB of RAM installed. I'm using the laptop for Flash development, basic Photoshop 7, and mid-level Final Cut Pro 3 on top of the usual word processing/internet college student use. Even with a summer job, I am somewhat strapped for cash at this time since I also need to be saving for next school year. I can get a two 512MB chips for $198 or a single 1GB chip for $316. It seems like it would be better to just go ahead and get the 512MB chips because I should be able to cover that on one week of pay. I know that I'll have additional chips to sell if I do want to upgrade further, but it seems like 1GB is enough RAM for at least the next year or two until the 1GB chips go down in price. Am I thinking clearly here, or am I missing something important? Thanks all! BTW, I also tend to leave apps running rather than quitting them because Mac OS X simply does an awesome job of managing 10-15 application simultaneously.
