Seems a good deal to me. $29 per month for 24 months. 32g 6th gen iPad with 10gig of data per month then throttled to 1.5mbps. So that's $696 for the cellular iPad (currently $667 at officeworks) and 240g of data over the 2 years.
Plus I got $150 cashback through my work run cashback site, ymmv but that took my total down to $546.
I have a bunch of both Android tabs and iPads.
Apple make good hardware. They tend to perform well.
But if you're used to Android, you will get very annoyed at all the things you take for granted but cannot do on the iPad. Things like sending files to another device via Wifi-direct. WPS for wifi passwords. Plugging in a mass storage device. Plugging it into a computer to use as a mass storage device. Shooting photos in 16:9 (you have to crop the photos manually yourself). A universal back button I find very handy. If you want a tablet in wide screen, you can't get one from Apple. Even though their phones are wide screen.
