You should definitely consider a system with an SSD, since prices have fallen considerably over the past few years. SSDs speed up boot time, wake-from-sleep time, and the time it takes to launch a game and load a new level. Go ahead and get a gaming laptop with an SSD, but make sure you configure correctly. A small-capacity (128GB to 256GB) SSD with a roomy (1TB or greater) spinning hard drive is a good start if you also download the occasional video from the internet. (Only thicker gaming laptops will tend to support dual-drive arrangements like this.) Higher-capacity SSDs (512GB or more) are available, but choosing one will increase the purchase price of your gaming rig by a bunch. SSDs are very fast, but in terms of capacity, your money goes much further with hard drives.
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.
