I enjoy the iPhone primarily due to the fact that I now carry one device as opposed to three, cell, iPod and Palm TX organizer.
I did not get a data plan so I paid a premium for the phone.
For an 8G iPhone I paid $599 instead of $199. I sold my Palm TX for $225 so in the end I paid 75 dollars more for the phone with no data plan. When I bough my phone there were no plans at $15 that I could get.
So at $30 for 6GB per month over 36 months equals $1080 plus taxes brought it close to $1200 over the life of the phone, a cost that I couldn't justify. I don't need to be that connected to warrant paying more for the data plan.
I called Rogers and had them turn off the data feature of the phone so I can't use it by accident at the outrageous cost of $ 0.05 per KB.
The only thing I really miss about not having the data plan is the GPS needs the live data connection to calculate distance and load the maps.
If do plan on using the GPS I pre-load my route at home using Wifi.
When we were in Disney in August I set up a small Wifi network in our DVC accommodations and could use the WIfi feature on the iPhone to browse, load maps of the places we wanted to visit and update folks on

I wish the ringer was louder, there was a 5 MP camera in the phone, a cut & paste feature and FLASH support.
