Update: after about a month of using this bag I have upgraded my review to 5 stars.  Really solid and good looking, extraordinarily functional whether you are carrying just a few things to hit the coffee shop or your laptop and tons of stuff for work.

So I work in an office where everyone has a big clunky watch and fancy shoes, which is to say that the boring everyday black nylon laptop cases that Dell distributes to their corporate customers just don't cut it.

This bag really fits the bill for style.  Not quite as extreme as the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Oakley-Kitchen-Sink-Backpack/dp/B00793IVAM/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Oakley Kitchen Sink Backpack</a>&nbsp;but it has a very serious and functional look.

That said, it's got more bike messenger style than function.  It also lacks a waist strap or even a good location to add one (the second strap goes around your stomach to stabilize the bag if you were to be riding a motorcycle or bicycle)

This thing is PACKED with features.  EIGHT zippered compartments ( including a TSA compliant laptop compartment), five unzippered compartments, two Velcro compartments, key leash clip, reflector panels, Rollaboard hoolder with velcro, velcro holder for rollaboards, water bottle holder (located on teh outside, in case it leaks) Super soft pocket sized for tablets (one of the velcro slots mentioned above) three pen slots, and more more more!

Medium is a great size for taking a laptop, all your papers, a tablet, etc to work.  The laptop compartment is a tight fit for a 15.6 inch widescreen laptop, the older 15.4 inch laptops fit with a bit more room.  The  velcro closure is similar to what bike messengers use and allow you to have a reasonably secure velcro closure with different sized items. The mongo clip on the shoulder strap lets you easily tighten or loosen it on the fly.

The first time around it was a toss up between 4 and 5 stars.  My complaints:

1) Laptop compartment is not water resistant.  The main compartment looks to be fairly water resistant, but it's pretty obvious that the top zipper of the laptop compartment is not shielded or splash resistant.  This would have been a good place for a Uretek zipper.

2) Shoulder strap pad somewhat disappointing.  The webbing is nice and wide (2") but the pad just doesn't quite live up to the rest of the pack - really needs a cell phone pouch and more padding.

3) Top handle needs more thought - it's concave on the wrong side and felt a bit narrow in the hand after walking with my laptop, etc for about 10 minutes (I didn't have the shoulder strap with me).  I also feel that a bit more structure attached to the handle would be good.

4) Base is a bit too narrow - the problem is that it really doesn't stand up well.

5) Metal buckles seem more for show than function - I think I'd only use them to lock in a coat rather than as a way to make the closure secure,  I'm more accustomed to having a fastex on the main flap. - strike that, after a few months with the Velcro, I think that it is more versatile than a Fastex.  I rely on the strap and extra buckles to hold a coat instead.
