I am considering getting the new macbook air. I have some questions. Based on current models. 1) Which is better/better value? 11 ultimate, 13" base with *few* upgrades? 2) does iLife come with powerpoint? 3) if Not is keynote just as easy to use/learn (This would be my first mac) 4) any must have accessories? 5) is the external superdrive worth the *huge* price? or will any external usb 2.0 dvd drive work? (links please) 6) do you know of any cheaper non-apple adapters that work just as well (like this; I know this website is not a scam btw for anyone who wants to buy something: http://www.dealextreme.com/p/micro-dvi-to-dvi-adapter-23289) 7) any good cases or cool gadgets I should look at 8) random: how to take screenshot on mac? A lot of these questions have been anwered but any help would be VERY appreciated.
