Although we're all upset about the 2.2 update, or lack thereof, I still want to say something nice about my Captivate.
I think it's the best looking Galaxy S phone. I appreciate it's physical design and shape as opposed to the knock-off iPhone looking style of the Vibrant, Epic, and Fascinate.
Also, I wanted to pass along that running the GPSRestore app provided by Samsung DID improve my GPS capabilities. Remember to first make sure you're updated via Kies, then run GPSRestore in a clear open area where it can get a good lock on you. So far so good, it's been dead on. I understand this may not work for everyone, but it did for me.
