Hi, I'd like to install SL on my macbook air 2.13.... but I have a couple of questions for you, who already did it... is the "spotlight search window" still flickering during a research? (it seems a problem related with SSD machines in Leopard) is it now warmer? colder? same? how about the fan? Did you notice changes in the way SL use it? battery life? this machine with SSD is pretty snappy... is it even faster now? please feel free to add any other relevant information i didn't cover with my questions (odd behavior, new problems, etc.) thanks very much M.
