hi guys, i'm thinking of maxing out my macbook unibody's specs, plus buying an extra battery. (i have 2.4Ghz with 250 GB mem and 2 GB of ram). i inquired about the prices of maxing out my specs (thanks Charlie!), and now i'm confused as to which upgrade is important for my needs. definitely i'm going to upgrade little by little, but i need your advice as to which should go first. my needs are fairly simple: - i mostly use word processing applications - i use sun wireless broadband - i use USB ports often for my ipod, sun, memory card reader, etc. - i surf the net several hours a day, with safari and firefox both open, and both running 1 or 2 flash games (hehe) - my battery is down to 92 cycles since feb of this year - i'm highly mobile here are the things i'm considering: 1) Battery for Macbook unibody 2.4Ghz 2) RAM upgrade from 2GB to 4GB 3) Memory upgrade from 250 GB to either 320GB or 500GB i need your advice re: which should be prioritized based on my needs i also have a few more questions: 1) does upgrading the RAM put less stress on the CPU for flash applications or USB devices, and consequently, less pressure on the battery? 2) what happens to my existing 250GB in case i go for a memory upgrade? how do i back up my files, etc. if i don't have a spare hard drive? thanks in advance!!!
