I just wanted to report using the onboard gps on the 910c.
I went on a trip down to Florida (looking for work) last week for 9 days.
When I landed in Orlando, I started the GPS in the rental car, using some old Dell gps software from my old Dell Axim x51v on the HP ipaq 910c. It took a couple of minutes to lock, of course this would be normal to any gps, since I flew down from Massachusetts. After that, any time I used it it would lock on within a minute.
I also used it with an auto power adapter by iGO, you need a power adapter if using the GPS for extended periods, otherwise you will totally drain out the battery.
I also used some gps software by Memory-Map (
Memory-Map: GPS Mapping Software for PC and Windows Mobile), for my photography trips on the weekends. I downladed some Tiff files from the USGS, they were aerial photo's of areas I planned to be in. I do wildlife photography as a hobby, and I wanted to use the aerial photo's to find paths to use while out in remote areas. It worked great, I could make out groups of palm trees on the maps so I could tell where I was on the ground.
Just wanted to let everyone know that it works great.
On a side note, I don't use the keyboard at all, if the 910c didn't have the keyboard or had a bigger full size screen with an on screen keyboard, I'd be a very happy person.
