There's a curious post on Sans Mirror today, talking about camera/lens updates: http://www.sansmirror.com/newsviews/the-firmware-update-woes.html. I'm not sure whether it's written by Thom Hogan or someone else (sounds like someone else), but I really can't relate to the problems the author appears to have with camera/lens updates. With the Olympus Digital Camera Updater (I don't know if Panasonic does it this way), the updates are simple and easy, just connect your camera lens combo to you PC, open up the updater and it interrogates and recommends any updates. Swap lenses and do the same for your entire kit. The updater clearly identifies the camera/lens attached, the current firmware version and whether newer versions are available. What could be easier? So to lump all mirrorless systems into this supposedly one boat, as opined in the article, is actually pretty poor.
