While I haven't purchased my E-3 as of yet - I did get a chance to quickly test one when it was first introduced. It looked like a camera that would suit my needs well. The 12-60 lens that I tested with, so impressed me that I purchased one along with an E-510 body to take with me on my lengthy excursion to Costa Rica during February and March. It is a wonderful piece of glass with excellent close focus abilitiy. This was the post I made based on my initial try of the E-3 and 12-60mm:
Olympus E-3 - I’m In Love : Outside The Box
Probably kind of long on the tooth now since so many have purchased the E-3 over the last several months and have made their findings known.
