Each gaming mouse will have a DPI range (e.g. 200 – 8,000), and the user can select a point in between that feels comfortable. A very high DPI would be something like 16,000. Most office mice will have a DPI of well below 1,000, by comparison. The majority of gamers will find 800 to 3,000 comfortable, but you can train yourself to cope with higher sensitivities over time.
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
