I have an 11 inch 2GB Ram 1.4 Ghz Macbook Air, and over the summer I upgraded it to Lion. My air just kept shutting down on its own frequently, and the lag was atrocious. I quickly reverted back to snow leopard and haven't tried Lion since. Have these bugs been resolved? Is my air just not very compatible with lion? The main reason I want to upgrade to Lion is so I can sync with my iMac easier, and so I can use iCloud with my touch and iPhone. Any suggestions on this will be greatly appreciated!
