This is the bag I've been hoping someone would make. This is three-in-one modular bag made by Ohmetric, a new brand from Allsop. Slipped inside a compartment in the back of the pack is a laptop sleeve with a plastic lap tray attached too keep the hot battery from roasting your thighs. Inside a front pocket is a vertical organizer sleeve with four peripheral pockets. When you're on a plane, you slip this out to keep your toys with you at your seat while storing the bigger bag in the overhead bin. And there're plenty of top and side zipped pockets.
Inside the bag are two other compartments, side pockets, and a chest strap to releave the stress on your shoulders when you're schlepping your laptop all over creation, say, something like CES. Thank-you!
The three-in-one bag will cost $139.99 when it becomes available in April. A separate attache-like peripheral organizer sleeve will cost $49.99.
