Ok I've been playing around with Lion for a couple hours now. I'm not exactly sure what resume does. I thought when you x out safari and then bring it back it should leave you right where you left off. Doesn't happen. Second, versions...how does this work i see it nowhere. third, i have airdrop on my MBP working but it doesn't show up on my iMac with Lion. The iMac has all the requirements however even in its preferences it doesn't let you add airdrop to finder. someone help me out here.
