Hey, that's super, and far be it from me to dole out advice in regards to what people do in their own beds. 
A $99 Android tablet is a better solution for the "cookie recipe" types, and that's just fine. Sure beats paying $700 for an iPad to sit on the crapper playing Candy Crush like a good majority of iPad users do.
HP ePrint works terrible for me on my iPads, I know that much - and corporations still prefer wired over wireless anyways. I've used the Lantronix solutions with far better success. AirPlay (AirPrint) is not big in the enterprise by any stretch.
Duce, You hit on a another huge point for me and why I don't use Apple product, besides being a nearly vertically integrated monopoly, they don't follow standards very well. They also make their own "standards" that don't work with anyone else's products and are not enterprise friendly. (So much for a "standard.") AirPlay uses Bonjour which doesn't handle being routed, unless you spend for custom networking hardware, etc. It's a nightmare for Enterprise support and is really obviously designed for a home user single subnet network.
If someone likes Apple's closed ecosystem great but as you say, comparing a media consumption tablet like an iPad or Android Tablet to the Surface 3, isn't a good comparison.
As you allude to, did the iPad print to standard existing printers or did people need to go buy a special iPad compatible printer? That's not a standard, that's the tail wagging the dog. It only happened because Apple sold enough units that big companies said, well we better add Apple's custom protocol to our printers. With the trend in Apple iPhone and iPad market share, we might just see a time when large vendors don't think it's worth developing custom Apple only products.
So you end up with Enterprises needing solutions like NetIQ's Mobile iPrint servers solution, so that they can support their existing enterprise printer infrastructure, instead of Apple just supporting the standards based IPP(Internet Printing Protocol) system like virtually everyone else. The same can be said for Android printing, just so you don't think I'm only calling out Apple for not having Enterprise support in it's media consumption tablets.
Both vendors could have come up with a standard based "IPP lite" to build into their media consumption OS, and created a new standard for the entire industry to follow. Then printers could have supported all the new media consumption OS devices, even phones for printing right out of the box without vendor lock in. This is good for us consumers and hopefully a few others open their eyes to Apple being far worse for the overall ecosystem than other big vendors.
