Case Logic 16 or 18 Inch Black Laptop Case (PNC-218)
I needed a laptop case that was wide enough to fit my awesome illuminated wireless keyboard I use with my laptop (keyboard found here). I got the 18 inch version (You can change it to 16 once on the page if you do not plan to tote a keyboard). This case has lots of pockets and an adjustable slide to fit different sized laptops. Has a side area for my mouse and headset. And a zip pocket areas for my paperwork and other junk. Anther nifty feature worth pointing out, are the back straps to attach it to your luggage as you travel (illustrated in the sample pictures on Amazon). I do use a WiFi dongle on my laptop and always take it out just in case.
