I'm not posting a full review yet, as I'm still working out the kinks. I liked the idea of this product, and it was reasonably priced, so I registered in early June. The earlier version couldn't track my location at all, though I suspect the problem was at my end at the time. After giving the new version permission to track my location, it accurately tracks my IP address (which will allow tracking accurate within a 50km radius), but it consistently reports my Mac as being on a causeway in Miami, Florida, when it's actually in Eastern Canada. At least it's on the right continent and the right coast! Unfortunately, the error isn't on Orbicle's end, as near as I can tell; the ability to chart the location of your Mac/iPhone/etc. depends on Skyhook coverage, and for some reason Skyhook apparently thinks I'm thousands of miles from my actual location, despite providing accurate data to them on June 3rd. I suspect most US users won't have this difficulty, as Skyhook coverage seems to be pretty good in most populated areas of the USA. I've got a request into Skyhook to see if I can correct the error at their end. Meanwhile, I just hope nobody steals my laptop, or the cops in Miami are going to have a fun time finding it!
