GPS on the iPad is AWESOME!!!!
I think the GPS is FANTASTIC!!! But, I do a lot of spelunking, and even the 6" Dash mounted GPS is only soso...although TONS better than what I had before that. I have the iPad "mounted" in the car so that it is below the in-dash GPS. Which means I can either NOT use the car GPS and leave it on video/audio, favoring instead to use the
I have also been using the iPad on my little 14' flat bottom boat as I troll around the swamps and rivers in the area. VERY helpful. I realize I could use a variety of GPS units that I have, from small hand-held to larger car mount with battery that would allow for hand held usage, but the iPad, with all of GLORIOUS 9+" screen is just amazing...not to mention the variety of the program I am using for maps (Google, Hybrid Satellite Imagery laid over streets maps)...and the connectivity to the internet. WOW!!!
As far as 3g, I have been keeping the unlimited plan going, but I can't use more than 2g that I can figure, and I am off during for the summer right now, and I thought usage would be higher. I did just spend the weekend in Houston and was on the road the whole time, accessing 3g a bunch. And, the hotel on Saturday night wanted to charge for wifi (WTF???) and I declined it and browsed for a couple of hours on 3g. Point is, the best I have come up with is about .5gb for the last two weeks including this past weekend.
But, for the time being, I will keep the unlimited plan...but come this fall, I will probably drop to the $15 plan.
But, I did consider that there were a bunch of other plans, but they were all MORE expensive...and the Apple iPad 3g is still the best plan. Besides, who wants to be tethered to another device? I just spent the last 16 years tethered to a laptop power cord, mouse and lap-rest...and SO glad to be FREE of those things that were keeping me bound down!!!
