Rated 1 out of 5 by from Same quality issue as other reviewer Like another reviewer, my bag almost immediately began self-destructing. The blue version has a vinyl like coating that begins to crack, wear, and flake almost immediately. Contrary to Timbuk2's comment, it is not "merely" cosmetic (as if appearance issues on a bag this expensive can be dismissed with "merely"). The broken points also allow water to enter the bag. I have only used this bag for commuting on the train. Most of the time it spends in my lap like a baby. I bought another cheap convertible backpack at the same time that has had no issues. If Timbuk2 is not going to stand behind their bags, you should find a company who will.

Rated 3 out of 5 by from It's an ok bag I bought this bag to travel on overnight and day trips. I liked that it has both the traditional briefcase and backpack straps and can be used either way quickly and easily. That being said the bag is decent, I have a 15" Dell and it is a tight fit but it works. Main compartment is good size but not enough segregation for me. Would like separate compartments for charging cables, power supplies and misc cords and another for paper (books, notebooks, presentations, etc.). As it is I separate my computer and put everything else in the main compartment. If you do not have to carry paper it would be a great bag.

Rated 5 out of 5 by from Solid Messenger Bag! Great computer bag all around.On my second one finally after 2 years of abuse and travel. Slim even holding my 15" MacBook Pro, an iPad, and a few other gadgets. The hidden backpack feature is awesome to have when I need to even things out on my shoulders. Literally the only small thing that bothers me about this bag, is the front D ring that the shoulder strap hooks to. It has enough play that it keeps spinning around causing the round part to go upside down. Wears the fabric a bit faster that way it seems. Other than that, looking forward to buying another one of these when this thing finally wears out!

Rated 5 out of 5 by from Fit Everything I'm a graduate student taking classes and working at an internship. While at "work" i use the messenger strap to look more professional but while commuting and walking through the city it's so convenient to switch to the back pack straps for easy maneuvering through crowds. Ive actually stopped on the street and changed straps without having to place the bag on the ground. This bag fits Everything i need: laptop, notebooks, textbooks, etc. It gets heavy but I think that's more a function of what I'm hauling not the bag itself. This bag is going to come with me from school to profession, easily.

Rated 5 out of 5 by from One bag to rule them all I searched a lot - trying to find a backpack/messenger bag-combo that would be useful for commuting but also look good in business scenarios. Finally, I found the best alternative! I use it as a backpack when I need to carry my work laptop or my chromebook (11"6), or back/forth from the kindergarten trying to handle two kids at the same time. At the office, I switch easily to the bag/messenger bag option. The blue voodoo color is really nice! I do (as others have mentioned) sometimes miss a dedicated place for a water bottle, but so far that is the only con I have found. Before I used to switch back and forth between boring, big, backpacks and more stylish office bags, now I only need one bag!

Rated 3 out of 5 by from Ace Laptop Backpack Messenger Bag To start off with the size of the bag as advertised is incorrect. It is much smaller then posted on their site. This ACE bag is advertised as 1700cu in. and is actually closer to 1000cu in. The ALIBI bag is advertised as 976cu in. and is actually closer to 1400cu in. They seem off an a lot of their bag sizes. I use this bag for my everyday work commute and as a freelancer I pretty much carry my office with me. I try and limit what I carry to stay light. However the minimal stuff I do carry for some reason fill this bag pretty quick. The bag should be made a little wider and taller. Depth is good. This bag is too small to be a backpack. You can get rid of the shoulder straps to lighten the bag and that pocket becomes an additional back pocket. What would be good is if the front pockets would expand out from the bag instead of filling into the bag which takes away space from the main compartment. Also for some reason the pockets for the pens and small stuff is installed on an angle in the back because of the backpack aspect but this is stupid either way. Just install these pockets horizontally.

Rated 4 out of 5 by from I love it, but... I am definitely one of those types that take all their gear with them everywhere they go. Up until now it has usually been in backpack form. When I came across this hybrid I knew I wanted to try it. With all the different compartments it does keeps my stuff well organized. I am able to carry my books, laptop, hard drive, and files, etc. all together in one bag. As I said before, though, the hybrid factor is the first thing that attracted me to the bag itself and I have to say, overall it works pretty well. However, I wish they could have disguised the fronts zips more. I find it a little on the bulky side. And tucking away the backpack straps is a little bit cumbersome, but definitely not a deal breaker.

Rated 1 out of 5 by from Do not buy this bag. I wanted a bag for an office job so I bought the ace bag. I kept it clean and neat but unfortunately the material at the bottom broke (split up, dissolved)after just three months of normal use! I've sent the photos to timbuk2 but they said that this is just a cosmetic thing and normal wear!? If broken fabric is normal wear, then you should expect this bag to last for maximum of three months. Also, I think this company is fake and they don't care about their customer because they ignored me.
