Like many here, my Mini 9 has replaced my previous laptop (a Toshiba Portege Pentium Centrino). Having just finished my M.Div degree, I do a lot of research/writing papers. Nothing beats being able to carry my entire "office" with me to the library. With BibleWorks (and soon Libronix) installed, I can study the Bible in the original Greek and Hebrew, all on a machine that is about the size of a small Bible! I get comments all the time from fellow students about how small/cool my Mini is. Since the battery lasts so long, I can afford to sit through a three-hour class without having to worry about outlets or extension cords. And because the suspend function works so smoothly and well on Ubuntu, I can put my Mini 9 to sleep while my professor is explaining and then wake it up to take notes. The time from suspend to wake is that fast!
I also use my Mini 9 as a entertainment/media center. I currently have 8 Pixar movies, 4 Hayao Miyazaki movies, 3 Star Wars movies (Episodes IV-VI), and Kung Fu Panda on my 16GB SDHC card (I feel the need for a 32GB coming on...). It's like carrying my own Blockbuster with me. Not to mention my entire digital music collection on my 64GB Runcore.
I love the fact that the Mini 9 is small enough for me to take it along so that I always have it with me, without feeling weighed down.
