I went ahead and upgraded my Mac mini to OS X Lion yesterday and just wanted to see who else did it? If you believe the hype from Apple, it has over 250 new features, but in reality some of them are only useful if you have certain bits of hardware, like a track pad or external time machine device. Speaking of time machine, if you use a NAS as yours, don't upgrade to Lion just yet. One of the new 'features' that Apple didn't tell anyone about is that all time machine devices have to support the new Netatalk 2.2 protocol instead of older versions. Have a guess how many NAS devices support this new protocol?? The manufacture of my NAS (Synology) have their new OS in beta at the moment but there's no release date of the full version just yet. Cheers, Michael.
