With Lion's release, apple for me will have completed a full developmental circle, taking a limited but very capable tiger, and making it into leopard, a great and advanced os, then going to snow leopard for an interim release that solidified the capacities of leopard, and now to Lion which is without any doubt the best os this world has ever seen. I don't care that much about UI elements, although apple is making a lot of interesting modifications and additions. But I am very excited that core os functionalities, are being rethought, and paradigms that hadn't changed for decades are shifting. Case in point, the open closed apps paradigm. What a thing of the past right? Soon it will seem a distant memory how we used to have open and closed apps. Now the system itself manages resources, so you don't have to. Better over the cloud connection, file management and syncing...it's been a constant request of mine, but I am glad they took a bit longer because they are rethinking this from the ground up (as they should) with airdrop, and not merely offering patches. Very excited to see how this goes. And there are also evolutionary changes, that I won't go into here, but full disk encryption, (finally) some sort of resolution independence, etc. etc. And summer is just around the corner. Good times!
