I was a long time user of Anywhere Map. I've finally given up on in. The ipaq was too small for my 40 yr old eyes. The tablets were too big to fit in my RV-4. They are nice products with a huge user base. They have their own set of forums for helping each other out. Also, I never knew when my ipaq would work or not. It worked all the way to and from OSH but after I got back and wanted to go on a local flight, it drained itself somehow and was completely useless until I got it charged. The software itself has a lot of great features. I really wish I could use it. If you have any specific questions I'd be happy to try to answer.
