Frz, use the download script I linked. That way you don't need to let your tablet do any of the work. Just start it up and let it run. I've pulled down some 4 million tiles already and it's still going. I'm doing the zoom levels for the entire US from 16 down to 8, with the Michigan/Ohio area zoomed down to 6 since that's the primary area I travel in. It took me a couple weeks to get it all (kept having to restart the script because of my crappy internet connection causing the script to repeatedly bomb out) but I finally got it all and have been testing it in stages as I went, and so far, so good.
