I have an 11.6 ultimate config... but I still find the 128gb SSD tight, with a large bootcamp partition. Also I feel like storing media on the SSD is kinda wasteful of the SSD's speed. So I've done this temporary solution. I figured other people would be interested. I tried 2 items, as I wanted to add storage via usb without having it stick out and stuff. The 2 I have are the Elago mobile nano II MicroSDHC usb 2.0 drive, and the Lexar echo ZE 16gb version Elago Mobile nano II for 8$ at amazon Lexar echo ZE Here are both drives on my macbook air for size comparison. The nice part about the elago is that it the connector fits entirely the usb port making the drive sit flush against the usb port which means it sticks out 5mm from the side of the air. The lexar drive however has a connector that sticks out from the port, making the whole drive stick out 10mm from the macbook air. Performance wise, The lexar drive is a decent USB drive, giving about 6-8mb/sec write and 10-15 mb/sec read for me. The Elago on the otherhand is completely limited to the class of microSDHC card you put in. ie 2mb/sec write if you use class 2... and 10mb/sec write on a class 10. These are both much slower than the SSD, but sometimes I like lugging like 16gb of movies without eating up write cycles of the SSD. If you spent a little more you could get a 32gb card or lexar drive, and for many people that might be enough for a itunes music collection. Obviously the best solution is to get a larger SSD, but those cost alot and possibly violate my warranty. So this is my stopgap measure.
