I'm on the verge of getting a touch and i have a question regarding the Maps app. I know you can look look up directions and what not while in WiFi range, but is there any way to take the directions with you? If I look up how to get somewhere and then get in my car, will the touch be of any use? Does it save the turn by turn directions, similar to the printout on google maps? Does it save any of the map images for use outside wifi reception? Thanks for any info. PS, with a new iPhone on the horizon is now a really bad time to buy a touch or would it seem a 2nd gen is still a ways off?
