A device lab is a highly functional way to provide handsets, tablets, and other Internet-capable devices to those interested in testing their work across a variety of screens and hardware. Designers, developers, content creators, and others can use a device lab to gain a better understanding of what users experience when visiting your site from these devices. By creating a device lab, you can empower your teammates to test their own work on real physical devices in an easy and intuitive way. Our aim with this book is to provide a Pocket Guide for you to keep as a reference, a companion manual to your lab as you purchase devices, sort out power solutions, set up shelving and a checkout system, and iterate on the lab’s usability. We hope to save you from many of the headaches that we encountered as we continued to iterate on our own lab, and to equip you with the tools to build the best possible user experience for your device lab’s users.

@craiginwales Thank you for that response. My brain is like 5 year old most of the times :-)

I read the copy a few times and I am still a little confused. I see "device lab" used 100 times and I still do not know what it is. @craiginwales If you were to tell a 5 year old what device lab is. What would you say?
