Thanks you. I think it's just the thought of having a clean installed system and get the montain lion thumbstick with the air is better than having the lion version then upgrade if there's a reinstall needed (if that ever will happen true).
But I'll guess I pull the trigger in the weekend. I'll get the 11 version since I want portability but sadly I will do lots of music and sheet music writing so I'll be mostly working on a second screen when not on the go (which is yet another investment. But I think I will just simply have to test this setup out).
Thanks
Fred
There's no more recovery thumbdrive anymore. You reinstall from the recovery partition or the internet recovery in the EFI.
ML sounds like it is going to be a pointless upgrade anyways
