I have an iPad2, which I'm getting to the point, I don't leave home without it. I use mine for a chip reference of my own making. I have my Kentucky illegals and antique poker chip photo project loaded on. While out at yard sales, I have shown some people what it is I'm looking for. After we move away from the puddle of drool, It's leads to conversation and to leads of who they know that might have some old chips. I just made PDFs of my stuff on my computer and then emailed it to myself on the iPad and downloaded it to the iBook library, which has a PDF option.
