[LAU] iPad and Linux audio

Hi :) sorry for the cross posting. I'm interested if there's really an important usage for Linux (especially audio/MIDI), perhaps within the limits of a jailbreak, for an iPod. Someone from a Linux mailing list already sent me this links: I won an iPod 2 and I flirt with selling it and then to buy some Android thingy instead. I own a KORG nanoKONTROL, costs less than 3O €, so I won't keep an iPod for more than 600 €, providing not much more than the same features. To safe costs for ink cartridges an e-reader would be able to do the job. In wonder if there are really important realtime abilities provided by an iPod 2 that can be used with Linux. At the moment I'm using it with VirtualBox, running something very annoying, to use this tabled computer. Perhaps somebody has experiences with iPod vs Android?! Regards, Ralf
