I'm looking for a sturdy messenger bag type thing that will protect my new 15" powerbook and that also has room for a few college books and notebooks, along with my laptop accessories, while still looking nice and feeling comfortable. The two leading contenders that I've found are: The Radtech Curve Brenthaven Fusion Flex Messenger Case Both are about the same price... (the Brenthaven is $79.95 after the Apple student discount). My question is, does anybody have experiences with either of these and want to offer their opinion? Both seem like nice, sturdy bags... I guess my biggest issues that I haven't been able to find much on are comfort and space to carry around other books. Also feel free to throw out any similar options in the same price range. Thanks in advance!
