I bought the Booq Bag and returned it after a day, because I didn’t feel the protection was adequate. I finally broke down and bought the Brenthaven Case with removable sleeve as it is definitely "bullet proof."
A good blend of style and protection would bee one of the Acme made bags...but in my opinion, nothing beats a Brenthaven! :-D
[and no I don’t work for Brenthaven]
