Currently I'm debating on the STM Impluse backpack that I purchased or return it. It's an awesome bag but, I work from home and will probably only used it less then 5 times a year for traveling. What I currently have as well, Brenthaven 13inch zipper padded sleeve, Speck case, STM wire/cable case, and a Nike Sling cross shoulder bag with a padded pouch. So technically I do not need this the STM Impulse backpack. It just looks cool, and is supper comfortable. Although it was only $89 (at a local store) I want to make sure there is a use for it.
