Its a really slick app, it works and the staff at the Apple shop said that the Windows Rugged Handheld devices they used to have (symbol and Sequia) were always failing and too slow. They even use the Pogo capacitive stylus for signature capture (trust me we have these stylus here and they are god awful) but they say using these occasionally is far better than using the old devices the whole time.
I’ll check in at the store later in the year to see how they are holding up!
