I'm happily running 11.10 on a macbook air 4,2 and have been doing so for a while now but I'm tempted to do the auto-upgrade to 12.04 since I'd like better multitouch support (everything else works pretty damn well now) and maybe better battery life.
Has anyone done an upgrade and can recommend for/against doing so. I've run the 11.10. post-install scripts quite often (after updates, etc...) so I'm a little worried its modifications to the base configuration might conflict with the automated 12.04 update.
Normally I would just try it and sort out any issues but I'm on the road for another few weeks and I need my laptop to work so I'm weary of any issues...
I'd be grateful to hear of how others have weathered the update. Also is the macbook air better in 12.04? i.e. battery or trackpad.
