Hi all, thanks for reading. I find myself in a bit of a pickle. I'm a poor student who's ready to purchase a new MacBook, and I want to save as much as possible. Now that the new MBA have 4GB of RAM standard, I was wondering if the base model is worth considering. I plan to store most of my pics/videos on an external USB drive (3.0 transfer speeds!), making me strongly consider that 64GB of storage is adequate for everyday use (I know it's really like 50GB after Lion). What say you? Is the SSD upgradable down the line if I desire? Has anyone made do with the 64GB in the past and can share experiences? Thanks!
