Guess that's why they killed it - people remember it, but didn't realize it was still around - you certainly don't see it advertised anywhere.
Well, there were really two reasons why it died. First, it required a windows machine to run, and until recently none of them have really been that nice to use in the car. You need a combination of battery life (in case you forget the charger, you won't be able to get another cheaply and you're depending on this thing, remember?) and form factor that just wasn't there. Second, even when it was brand new it was out of date, so why buy it new? If you bought one a year old you could get it for $20 with the GPS dongle. If they had actually put in the effort necessary to keep it up-to-date, then I'd have paid for it when it came out, rather than when it got old. I've bought it twice now, a couple years old both times. It would fall on its ass anywhere around new construction, but it was pretty sweet for route planning and it was a cheap way to get an adequate GPS dongle.
I also bought Delorme's software a couple years aged on the same basis. It was better at turn-by-turn but the interface was atrocious and that made it worse at everything else. The GPS dongle is bright yellow, so I suggest the Microsoft package instead. Either one is adequate as a time source :)
