Floatin,
I agree. A few years back I was developing a custom application for the Ipaq that required GPS coordinates w/timestamp. So, I expensed a compact flash plug-in GPS receiver for my Ipaq. I thought it would be the greatest thing ever to have GPS integrated with my PDA. Well, it sucked. Perhaps it was the particular hardware I bought, I don't know, but it took forvever to acquire satellites, whereas an eTrex I had was quite quick about it.
My experience, which includes hardcore tinkering with gadgets, and major tests of my patience (I AM a Linux user afterall) has been that, like you said, the unit will present major problems at the worst possible time. So, after messing around with the Ipaq, I decided that dedicated GPS units are the way to go. The hardware and software in a G-296 for instance, are extensively tested and made for each other, and therefore rarely have trouble.
This iQue that John has is quite a leap in the PDA-GPS realm though. I was really impressed, and actually think that having some PDA features present on your GPS, rather than using your
PDA as a GPS, has advantages. You can easily scribble notes, listen to mp3s on long legs when you aren't communicating, or just stare at your friends' and family's phone numbers.
The iQue is different in that it requires no stylus to use the GPS features, it can be button operated just like a 196/296, at least while in the cradle.
