I had already decided on a laptop bag when I purchased my Macbook, but since I could only order the bag I was looking for (a Booq Taipan Shadow S), I opted instead to find a bag locally that I could get my hands on before purchase. I just like to be able to visually inspect any item that I plan to purchase, if only to let me gauge the quality before handing over some money.
On a weekend trip to MEC, I decided to pick up a very nice bag by Onsight, the Saigon Micro.
After looking over the bag, I decided to make the purchase anyway, as even if the laptop did not fit at all, the bag was still of fantastic quality.
Well, for clarification, when I did get home, I determined that the laptop pocket was in fact too small for my Macbook, but the bag was large enough to fit the laptop in a sleeve. Quality materials, several well designed pockets, strong and easily adjustable strap and excellent stitching really makes for an outstanding product. Even the interior lining has been thoughtfully designed, with a lighter colour fabric to make finding contents easy.
If you are in the market for a new bag, why not take a look at Onsight; they offer several quality products are very reasonable prices. A lot of manufacturers could learn a thing or two from them.
