I am curious how many of you transport your MBAs with a sleeve inside a bag or simply a bag. How much more protection will a sleeve offer rather than simply putting it inside a computer bag with a separate area for the laptop? I did pick up a Waterfield design sleeve - but it seems to add a little too much room to my bag rather than just putting it in the bag without the sleeve. Just curious what everyone on the forum does and also some thoughts I might not of had on the subject. Thanks in Advance!
