The Samsung model that came out late last year is quite nice. It's a small, light, inexpensive web terminal on something approximating hardware designed to be a Chromebook. Other Chromebooks have been older, heavier, weaker, and bad battery life laptops that aren't a good hardware fit. And the Pixel is probably too high end to justify right now with the limitations on the software. But I find the Samsung hardware quite nice, and the system is perfect for my family. We all have google accounts, can switch seamlessly between them, and I don't have to worry about any of the things you need to worry about with a Windows or Linux box. We keep it's charging station on a table next to the TV next to a Nexus 7. At any given time one of the devices is usually in use by somebody. I highly recommend this for anybody who doesn't need more than a web terminal and doesn't need MS Office. It's all my kids will need for most of their schooling.

Also, at $250 I don't mind letting my 5 and 7 year olds operate it all over the house. If it breaks, I'll just buy another one. Same with the N7.

Most of the people who complain about the Chromebook are trying to use it for the wrong thing. This is a spare computer you have sitting around for ANYBODY to pick up and use for 15 minutes, including guests. For power users it's not a primary computer.

We have had good success with retail "slat-wall" mounted on the walls all the way to the ceiling above our workbenches. It can support a lot of weight and there are a lot of ways to attach shelving or mount equipment using widely available brackets. And it will not deteriorate over time like pegboard. Also, it's attractive, which will help make your space look clean to passers by.

Also, have them give you lots of network and power drops spread around the room, you will constantly run out. Attach a lot of power strips to your furniture, etc.

You may want your own physical network separate from the rest of the building as well.
