New user here. Replacing travel laptop with ipad and wondering if there is anything comparable to ms Streets & Trips? Don't care about navigation and I don't want to connect, so it will need to use stored maps. On the PC S&T only required one CD for the whole country, so how big can it be? I bought a 64Gb ipad so should have lots of room. I know there are apps out there where I can pre-load maps as I need them...I'm hoping that's not the best you can do.
