A few questions.. What is this thing that people have been saying about the air's keyboard? is it too shallow or something, and is it supposed to be a disadvantage or a problem about the airs? Does putting a keyboard cover over let it have a 'deeper' feel? And does the cover have cons like preventing ventilation etc? And are any of you using microsoft office? I might need it for my essays + assignments but it is expensive.. near $100? Are there any free or much cheaper alternatives that work the same way as MS office and can be converted or is compatible for others using MS office on either windows or mac? I don't want this to become a problem when i need to send my work to classmates/teachers... Anyone know a cheaper alternative to apple's external superdrive too which has similar features and functions? Sorry about these questions, just about to get my air but thinking about the extras i'd have to fork out.. makes me wanna get a pro instead..
