I ordered a 8GB MicroSD card by Transcend from newegg. $16.59 shipped. I plan on primarily using it in my cellphone, but it comes with an SD adapter, so if I need to use it in the Mini, I have that option. Since I'm using my Mini primarily in the campus library, I can access my music and what not through Remote Desktop, which works fine on Windows 7 (I'm remoting into my Win XP Pro laptop in my dorm room). I feel a bit guilty about leaving the machine on in my room (needless power consumption, but I figure that if the hard drive's only being accessed while I'm remoted in, well, it shouldn't consume too much power while lying idle.
