BaseCamp still feels like beta software in many ways (on both Windows and Mac). As I said before, I think the Windows version is a bit more complete, and Garmin's Windows software usually leads the Mac. But it wasn't very many years ago when no GPS companies offered Mac versions of their software. Garmin is leading the pack with Mac support today - Magellan and DeLorme still have none.
I would like faster downloads and software that was a little more polished too - who wouldn't? But all things considered, BirdsEye is a great deal. Even if you want to download large areas (like Guy and me), it's not all that hard. You just make a point to start downloads when you're headed out of the house for work, or going to bed. They will be there when you get back. You can also queue up multiple downloads, and the second one will automatically start when the first one completes.
Garmin used to let you download larger areas in one session, then they restricted the file size and everybody stated complaining on their own forum. Personally, I never thought it made much difference. With the big downloads, they would often freeze halfway through and you'd need to start over from scratch. Downloading the smaller files usually didn't have this problem.
BTW, we are lucky that Garmin's using the NJ 2007 imagery here, since the quality is excellent. In other areas they use Digital Globe Satellite imagery (the NJ imagery was taken from airplanes). Many people are very upset by the low quality of the Digital Globe imagery, but I think it probably varies a lot by location.
Enjoy the Oregon and the aerial views.
