Previously, I had used a backpack designed for laptops to transport my computer--but I was looking for a more traditional carry-all when I came across the Belkin Dash Toploader. While there are definitely more luxurious products on the market, this is a practical and lightweight bag that has just enough extra storage to make it a cut above average.
In addition to a generous interior compartment, which is divided to provide support to your computer, three sides of the exterior have storage areas as well. The interior also has a couple of pockets including one with Velcro. The exterior edge of the bag has a pouch suitable for a small beverage bottle--a little too small to be of use to me--but if you have compact bottles, it'd work. One exterior side has two large flat pockets and the other has a large area with interior storage and two smaller pockets. All in all, it's an impressive amount of space for such a compact unit.
Of course, the interior of the bag is padded for safety. A detachable shoulder strap is of use as well. Honestly, this bag isn't some new and revolutionary new marvel--but it's a simple and solid design that is convenient for everyday use.
