AFP Out Of Date In OS X Lion

They may well make comments about this at some point. I don't think they need to make a comment before releasing a public beta, but if they do I think it could come after a production Mac OS X Lion is released possibly as early as next week. It's pretty clear that over the years of ReadyNAS history NetGear does all the updates it reasonably can to NAS devices to keep them compatible with newer OSes, add new features etc. The current firmware for Sparc devices works with the very first ReadyNAS devices released several years ago.

WhoCares?'s comments make it pretty clear there isn't a hardware limitation so I see no reason why they wouldn't want to add Mac OS X Lion support to the Sparc devices.

You may well find that you use software, peripherals etc. that aren't updated for Mac OS X Lion support yet. It's not unreasonable for there to be some delay after a major OS update before support is added. Anyone using their computer for business (apart from IT work that requires testing/work on the latest and greatest OS) would want to wait a little while for issues not picked up by beta testers to be sorted out and stability of the OS to improve.

If you choose to run Lion now, you can still access files on the NAS over CIFS.
