SkyDemon on iPad3 has been perect for my needs - realtime NOTAMS/METARS/TAFS, graphical profile of intended route, automatic FPL filing (free if flying through R112 during Olympics), automatic W&B calcs, endurance calcs, flight logging, etc. etc. I used to use a Flymap L with scanned 250000 and 500000 CAA charts, but the vectored SkyDemon charts are MUCH better. Take the 30 day trial - you'll sign up within a week
