I am installing it on my 11' 2gb as we speak. Hopefully it would reolve some issues i had with office 11. And be faster. Will let you know when it finishes and use it a bit
I did it yesterday, upgrading from Snow Leopard. Some gestures are impossible to get back, but I am quite pleased with the new OS. Installation was painless & I haven't had one issue.
Went from Lion on a 13" 2010 with 2 gb ram to ML. Seems ok, but it doesn't seem snappier nor slower. I didn't really use safari in Lion, but Safari seems nice.
Always best to have the latest anyway? As long as the performance doesn't decrease I mean.
Just upgraded my 2010 11" MBA to ML this morning. Did the quick and easy upgrade versus clean install and I have to say I am pleasantly surprised. The performance is about the same and my CPU temp is actually running about 5C cooler.
I still have a lot more use and testing to do before I'm completely sure about ML on my 2010 11" MBA, but so far it is looking really good.
