UPDATE: YOU CAN READ ABOUT MY EXPERIANCES IN 12 HOURS HERE: http://forums.macrumors.com/showthread.php?t=843886 UPDATE: FIND OUT HOW YOUR BATTERY COMPARES TO OTHERS HERE: http://forums.macrumors.com/showthread.php?t=844645 Hi All, Some of you may have read my experiances in the first 12 hours of owning my Rev A MacBook Air. You should probably read that first. Now, following on from that I have settled in a bit more and starting to DO things. I really like the clean look of OS X. The overly complex animation of glowing buttons etc on Windows 7 makes the whole experience feel a lot faster. So far, I haven't noticed any problems with the speed of the machine, I understand comparing it to the rest of the MB line its slow but so far I can run GarageBand and surf the net along with YouTube just fine. I have found, however, that read/write speeds are a little slower. I have 7200RPM Disks on my desktop and I had an SSD on my little ol' netbook. So this is a bit slow. An upgrade for that will definitely be on the cards. 32GB or 64GB SSD will be fine for me, as most of my DATA is on a 2TB NAS so only program storage is needed! Battery has come to my attention and I am interested to see what other people are getting... On my very rough timing I think I managed about 4 hours of mixed browsing, installing programs and GarageBand. Which seems pretty good! In another thread I will post my CoconutBattery Stats and we can all compare! All in all, the problems I had in the first 12 hours seem to have worked themselves out and I am starting to enjoy what a Mac can do. iLife really is something special! Thanks, Joe.
