Hi, Model: Macbook Air basic model. I recently got my Macbook Air and I was a little hesitant as to if I should return it and grab the new Macbook Pro but looking at the changes, I am better of with my Air. 1. I want to install Win7 and I was wondering, do I have to upgrade the RAM to 4GB for it to run smoothly? or it wouldn't make a difference? My needs are basic and not complex, the only reason I want Win7 is because there are some softwares that don't run on Mac and I need. I will be using BootCamp and not parallel. 2. What Win7 do I get, 32 or 64 and can someone please explain the difference and why is it I have to choose b/w those two for the Air. 3. Is there a way to keep my USB connected even if the laptop is in sleep mode? Sometimes I'd want to charge my phone yet keep the computer in sleep mode. 4. How do you keep the settings of your energy saver? I usually keep the computer on whilst being charging and turn off the monitor. Thanks a lot!
