Ok, it's iPad vs. paper charts at Ten paces. I use Ozrunways, Naips for iPad, and Goodreader for reading .pdf's.
With my iPad i can flick from Aviation weather, to flightplan, to WAC, VNC, VTC, ERC, DAP the entire AIP and of course any ERSA entry and back again in less than Ten seconds.
Then I have the "Goodreader" App. Under that I have the VFG and all capital city guides (being a lowly bugsmasher person). I also have a complete set of checklists for the aircraft as well as the entire POH in .pdf format (checked to match revision dates and pages numbers with paper POH).
The upside? I can spend more time with my eyes outside instead of fumbling with paper.
The downside? If this thing fails or runs out of battery, I'm in trouble without paper.
