But for the rest of us that like this kind of stuff i think it will be great. It's a sealed unit which means you don't have to worry about dust or shocks.
Anyone use ihike here? after getting my iphone, I'm looking to free myself from the pc world and would like to get an ipad for gps use in my 80. Anyone use this yet? for $7.99 I may download it on my iphone and give it a try this weekend.
I'm skeptical about a multi media device doing a good job as a GPS. I know that the iphone and ipads are wonderful things but using them as GPS nav units, I don't know. Aside from the hardware limitations, I'm having a hard time imagining interacting with these units on the trail. Just using my Iphone google maps on the road is s***ty enough to dissuade me from using it as a trail gps.
I use topo and street mapping software with which I interact a tremendous amount while wheeling. Lots of routing, re-routing, typing in waypoints (not just short words, but actual phrases), switch between 2D and 3D, etc are examples of what i do on my tiny laptop mounted on the Jotto desk. Granted, I've been brain washed by the PC world so that's all I know. However, having gigs and gigs of 10 min and 7.5 min maps loaded into my HDD for instant access is very sweet and I'm not seeing any multi media device come close!
Additionally, I don't see myself using the large off road GPS units either because interacting with them is such a chore for things like typing in waypoints, comments, etc. I love my Nuvi for point to point directions, auto rerouting functionality and of course, the sexy British female voice. But for a trail GPS, I keep falling back to the laptop. Even a tablet PC wont work for me due to my constant interaction with the mapping software.
Not so much a answer specifically about iPad, but a response to Wilson's post... I haven't used ihike, but I've used MotionX-GPS a fair amount on my iPhone 3G. It's pretty cool and at $3 it's an absolute steal of a deal. However, for off road use this set up leaves several key features that are less than ideal: 1) the iPhone screen is just too small to be of much use. If you zoom in to the level of detailed terrain necessary while on the trail, there's no enough screen real estate to give you the big picture of where you are. You need a bigger display to give both detail and trail context. 2) The built in GPS receiver is not sensitive enough, or when the iPhone is close enough for you to view screen, the receiver is shielded too much from a clear view of satellites to provide good tracking. The situation gets worse when under trees too. A separate GPS antenna or receiver "puck" is highly desirable. 3) As long as you've got 3G coverage and the detailed terrain maps automatically download things are great. But often times where I go off roading there's no cell coverage at all and you can't get the maps. MotionX has a map caching feature where you can download the maps you need ahead of time, but I've had mixed results with this feature.
On the positive side, if you've got 3G coverage and aren't trying to drive at the same time you navigate, it works great. And there's a way to email yourself map tracks in .gpx format and then load these into MotionX. I've used this feature to scout out a trail route ahead of time while at still at home and it works great!
