That's pretty crazy, but I love bags and have so many, that it sometimes feels like "the great game" is playing out before my eyes. I travel a fair amount, and really like to travel light. One of the things I like, however, is to have a laptop bag that has everything in it. This way, if I am traveling across the country, or even just across town, I will have everything I need with respect to the computer and my phone.I kid you not, I have used over a dozen different laptop bags over the years. Many have been excellent, and my most recent bag was a true favorite: the Ristretto by Tom Bihn. I cannot say enough good things about that bag, but one thing that was difficult was that it did not have a whole lot of pockets inside to organize the increasing amount of kit that I am carrying. Specifically, I carry the laptop itself, several different "dongles" (it's a new MacBook and only has one USB-C port, so I need dongles for giving talks like VGA and HDMI and dongles for plugging things in), the power supply and cords (I use the awesome USB Type-C, Anker Premium 5-Port 60W USB Wall Charger PowerPort+ 5 USB-C with Power Delivery for Apple MacBook, Nexus 5X / 6P and PowerIQ for iPhone, iPad, Samsung & More that can charge EVERYTHING from my Apple Watch to my computer with one brick!), some USB drives, a back up battery (also from Anker and also fantastic--but very big and heavy--Anker PowerCore+ 26800 Premium Portable Charger High Capacity External Battery with Qualcomm Quick Charge 2.0 and PowerPort+ 1 with Quick Charge 3.0 Wall Charger that can recharge everything including my laptop which is insanely awesome), some headphones, some business cards, some microfiber cloths, and some pens. It's not insane, at least I don't think it is, but it's a fair amount of stuff and it adds up, and I feel so much better if things are well-organized.So I was reading an issue of Cool Tools, a wonderful newsletter from Kevin Kelly, and someone was raving about this bag. Because I've gotten so many great ideas from that newsletter, I decided to think about it for a few days, read other reviews, and before long, I knew that I had to jump in.In short, this is a very clever system that can probably serve a lot of different needs. While there is tremendous flexibility in designing and reconfiguring bags, I am only using it as the B2 Computer bag set up, and that's what I'm reviewing here.It is a little bit tricky to put it together at first: you have to figure out how the zippers align and they are not the easiest to zip together. Once you get the hang of it, it's not very bad, and everything does feel very solid and durable. It's fairly compact, But it does have plenty of room. The laptop pocket is well padded, which is another complaint of some of the different bags I've had: sometimes it feels like if you set the bag down hard it could damage the laptop. That is not the case with this bag!Positives:-Looks good, if a little plain-Excellent padding-Fantastic number and layout of pockets for superior organization-Stands up vertically securely: this is a strange point, but many bags like this do not stand up on their own, but flop over. In fact, it's rare to have a bag this small that will stand up so stably, and I just love that aspect. If you're in an airport and just want to set it down for a second to reach into your pocket, it's so nice that you can just reach back down and the handle is there, rather than having to crouch all the way down and pick it up from the floor where has flopped over. In fact, my last bag frequently tipped over and that is how I lost my car keys: they spilled out when it tipped over and I didn't realize it! It was in fact this particular issue, along with the need for better organization that made me get this bag.-Has handle and strap (and both simultaneously) optionsNegatives-It's fairly plain looking-It only comes in black-it's actually fairly heavy: I think this is the price we pay for all the zippers and different compartments-The included shoulder strap is fairly crummy, I immediately replaced with a better one-The zippers seem to be pretty good quality, but I'm pretty sure they're not YKK-The included handle that is required to be used in the B2 configuration is clunky and heavy (they actually include a smaller, lighter, and more elegant and ergonomic handle with the kit! However, it can only be used when you're using it in the B0 configuration, something that I do not intended to do.)In sum, this is a pretty awesome bag. I think I will use it for quite sometime. We will see what I like and do not like as I put some miles on it. It has displaced all my other bags, however, which is saying something!
