I would love to see an app for the touchpad that allowed for offline reading of the chord pro format. These apps are great for musicians who need to carry a songbook of lyrics and chords. This is the only thing I really need my touchpad to do that it can't. Here are some examples...

App Store - SongBook Chordpro

App Store - MySongbook - Lyrics & Chords

SyncSing

LinkeSOFT SongBook Guitar Songs and Chords
