I've changed my mind (for the final time)... I decided to cancel my WiFi order, and order the 3G model instead. The $130 is pretty inconsequential, and I would have been upset with myself the first time that I wanted to turn on 3G during a trip. I also wanted the GPS. It will be worth the wait.

Jim, yeah, that 30 day extra wait will be worth it to me as well. I just know there will be times where I'll be like, damn I wish I had 3G on this thing
As for using a tethering solution, that doesn't work for me. MyWi takes up way to much battery power for my liking
So I'll stick it out for 30 days without an iPad instead of having an iPad for a 335 days without 3G ;-)
