Hello i'm new to Mac and this site. I bought my first MBP this weekend. the 13 inch with the i5 2.3 processor. I have some questions about upgrades. 1. I'm definitely upgrading to 8gb of ram. Has anyone used the ram from Crucial? Any issues? 2. I was thinking of upgrading the HD to a 7200rpm one. My question is would i really see a noticeable increase in speed with that HD upgrade? Also would the faster speed have an adverse affect on my batt life? SSD's are still out of my price range for now. Thanks in advance for the help. Sorry for any newbness errors in my postings.
