Castiv offers Guitar Sidekick for budding musicians

If you still do not have music flowing through your veins more than blood, then the Guitar Sidekick from Castiv might help sooth those stage jitters, especially since this device will connect to the neck of your guitar. Boasting an adjustable mechanism that will accommodate just about any smartphone size (the Sony PSP would also fit pretty snugly), it will help you see your notes as well as other references when playing without having to have someone else hold it up for you. No idea on whether an iPad version is in the works, but you can bring home the Guitar Sidekick for $30.
