I know that these forums are meant for issues, but I wanted to report my positive experience with my Edge 530 during my metric century ride today. I do not have the GPS chip beta from the forum installed, but I did bring it up to v4.10 a few rides before today's.
The metric century road ride was a 63 mile (101 km) ride through hilly, rolling roads of central NY (US). The battery started at 94% and was at 61% by the end of the ride. I had downloaded the course from the Garmin Connect website (through the Windows Garmin Express) to the GPS a few days prior. During today's ride I turned over navigation to the loaded, active course and every turn was properly called out with enough warning to make me feel comfortable that it was all working well.
Also, I had ClimbPro activated so all of the climbs (there were five of them qualifying for this feature) were annotated with the separate ClimbPro page. I laughed at the GO at the beginning of each of these climbs, as if I was going to ignite the afterburners. As I suffered up the bigger ones it was helpful to have the remaining distance displayed and really nice to see the CLIMB COMPLETED at the top.
Again, I was impressed by the 530's performance.
