Yes its worth it for itouch owners!

the value of this app became apparent to me this past week when i loaded a pq into my Garmen 60csx but neglected to load the approprate maps of the city i was in. doh! but with the pqs installed with geosphere working offline - with the offine street maps available - i was able to muddle through and my caching days were not ruined. so glad i spent the extra $7.99. thank you geosphere!
