I'm trying to decide on a small device 9.7 IPP vs. Macbook for taking with me while traveling and being in places without internet access. It seems that with the Macbook I can open programs and work in them and save the files on the SSD, and I can even have tabs open in a web browser that I can review while being offline. On an IPP I'm not clear on what happens if I am working in a program and want to save something without internet? I also do not think I can review open tabs in a web browser without it trying to refresh, resulting in me losing the content on the open tab because it is unable to connect to the internet. Are there ways to do these types of things on an IPP without internet also? Thanks.
