So I am a little confused with this flash storage. I'm not a techie, so please excuse the ignorance. I use my current laptop for music (about 8,000 songs), photos (3,000 photos), movies, etc. Will the flash be able to hold all this... say about 30gb of stuff. Also, is it reliable, or is it likely I will loose my work, etc. I am in college, so I do a lot of paper writing, sometimes 20-40 pages, and I don't really want to loose any work? Also, I'm confused if the lower end would be an upgrade or not, as it has lower Ghz. My current model has 2.2GHz Intel Core 2 Duo with 1 GB MHZ DDR2 SDRAM. Would I notice an improvement from my current mac to the new air? Thanks for the help guys!
