I'll just add that Easy Debian uses very little space in your main file system, so it can be used without cloning to SD. The image file that you have to download and extract (debian-final.img.ext2) goes onto your SD card.

The free space problem that is often discussed is caused by people trying to install too much stuff into their 1.1GB Debian image file. If you want to download tons of extra software, I recommend a partition. If you just want the included apps, and maybe a couple of small, extra packages, then you can probably use the image file.
