So in my last project, I discovered an odd match. I downloaded Kreg's bookshelf plans to my iPad so I could review their approach to assembling it.
And then I realized, it was a great shop device for following PDF plans. Don't know about Google 3D yet because I haven't checked to see if there's an app.
But... It's flat, easy to read, easy to handle. And, the screen adjust to scan and zoom so fast that moving around the plans was pretty slick.
Just kind of surprised by this. I assume other people are bringing their laptops or ipads into the shop for plans?
